delivered a concurring opinion.
Judge Meyers criticizes the Court for what he perceives to be an abandonment of the principle of stare decisis, claiming that “judicial conservatism is no longer in vogue.” To the contrary, it was the Gee-sa 1 court that failed to consider “the work of the great men” who preceded the Court, “consistent, coherent, and undoubted.”2 In Geesa, this Court overruled more than one hundred years of precedent3 without even a passing nod to stare decisis.
In determining whether precedent should be overruled, we should take into account whether the decision under consideration was itself a violation of the principles of stare decisis. In such circumstances, a judicially conservative court should bear in mind the consistent body of caselaw preceding the anomalous opinion when considering the application of stare decisis to the case at hand.
I join the opinion of the Court.
HOLLAND, J., delivered a concurring opinion in which JOHNSON, J., joined.
I concur in the majority’s decision to overrule the part of Geesa v. State, 820 S.W.2d 154 (Tex.Crim.App.1991) that concluded it was necessary to instruct juries on the definition of reasonable doubt. I also concur in the majority’s decision to overrule Reyes v. State, 938 S.W.2d 718, 721 (Tex.Crim.App.1996). I write only to express additional reasons in support of these decisions.
I.
Since this Court handed down its opinion in Geesa, members of this Court have subsequently questioned the wisdom of adopting the reasonable doubt instruction. In his concurring opinion in Reyes, Judge Meyers stated that the result in Reyes could not “be avoided after our unequivocal language in Geesa v. State, .... Such a result may, however, compel a majority of this Court to reexamine Geesa in the future and, were that to happen, I might very well join them in that endeavor.” Reyes, 938 S.W.2d at 722 (Meyers, J., concurring). Judge Meyer’s opinion in Reyes indicated that the issue of the continued viability of the Geesa instruction was not settled. See Shirley Baccus-Lobel and Gary Alan Udashen, Criminal Procedure: Pretrial, Trial and Appeal, 51 SMU L.Rev. 855, 871 (1998).
Two years later, Judge Womack followed Judge Meyers’s suggestion in Reyes and reexamined the Geesa instruction in his concurring opinion in State v. Toney, 979 S.W.2d 642 (Tex.Crim.App.1998)(Womack, J., with three judges, concurring). He proposed that this Court should overrule the parts of Geesa “that require this misbegotten definition of ‘reasonable doubt.’” Id. at 652.
This Court should not frivolously overrule established precedent. We should generally endeavor to follow the doctrine of stare decisis to promote judicial efficiency and consistency, foster reliance on judicial decisions, and contribute to the actual and perceived integrity of the judicial process. See Proctor v. State, 967 S.W.2d 840, 844 (Tex.Crim.App.1998). When this Court, however, comes to the conclusion that one of its prior decisions was poorly *575reasoned, or has proven to be unworkable in the lower courts, it would not promote •or preserve the integrity of the judicial process to leave that prior decision intact. See id. I believe this Court’s adoption of an instruction on the definition of reasonable doubt should be overruled in deference to analogous federal decisions, which were more soundly reasoned than our decision in Geesa. See Awadelkariem v. State, 974 S.W.2d 721, 725 (Tex.Crim.App.1998).
II.
In Geesa, this Court claimed that it was “evident that [Holland v. United States, 348 U.S. 121, 75 S.Ct. 127, 99 L.Ed. 150 (1954) and Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979) ] implicated the requirement of a full definitional instruction to the jury on reasonable doubt.” 820 S.W.2d at 161. An examination of decisions by the federal courts reveals that there was no explicit support for an instruction on the definition of reasonable doubt before the Geesa decision, regardless of this Court’s perceived implications of the holdings in Holland, or Jackson v. Virginia.
Thirteen years before this Court handed down Geesa, and after Holland had become part of the common law, the Fifth Circuit Court of Appeals reviewed a conviction wherein a Federal District Court instructed a jury on a definition of reasonable doubt.1 See U.S. v. Rodriguez, 585 F.2d 1234 (5th Cir.1978). The Fifth Circuit disapproved of the attempt to define or explain the phrase “beyond a reasonable doubt.” “There is no want of jurisprudence with respect to how the reasonable doubt standard may be explained.... Little new can, or should, be added after 200 years of judicial use of the same term.” Id. at 1241. The Fifth Circuit also warned of the pitfalls of attempting to define the term. “We underscore the gravity of misstating this ‘bedrock axiomatic and elementary principle’ whose enforcement lies at the foundation of our criminal law.” Id. at 1241.
Nine years later, and eight years after Jackson v. Virginia had become part of the common law, the Fifth Circuit Court of Appeals revisited the issue when it reviewed a death penalty conviction out of this State. See Thompson v. Lynaugh, 821 F.2d 1054, 1061 (5th Cir.1987). The Fifth Circuit concluded that,
although the jury must be instructed that the State bears the burden of proving the defendant’s guilt beyond a reasonable doubt, attempts by trial courts to define “reasonable doubt” have been disfavored by this Court. Such attempts often result in using the term itself in the definition and serve only to confuse the concept in the minds of the jurors.
From the Rodñguez and Thompson decisions, it is clear that the Fifth Circuit did not favor the notion that juries should be instructed on the definition of reasonable doubt.
III.
The pre-Geesa decisions of the Fifth Circuit, in addition to the explicit wording of the Supreme Court in Victor v. Nebraska, 511 U.S. 1, 114 S.Ct. 1239, 127 L.Ed.2d 583 (1994)2, demonstrate that this Court erroneously relied on the “implications” of the decisions in Holland and Jackson v. Virginia when we concluded in Geesa that it was necessary to instruct juries on the definition of beyond a reasonable doubt. Furthermore, when I consider the phrase “beyond a reasonable doubt,” I wonder why the phrase would need any explanation or definition at all. The small benefit, if any, which might possibly be gained by *576defining or explaining the phrase is overwhelmed by the confusion resulting from the attempt to define the phrase. One commentator observed that the phrase had been left without a definition for so many years to avoid confusing the jury.
One must assume the [Court of Criminal Appealj’s conscious exclusion [of a definition of “beyond a reasonable doubt] was for a valid reason — perhaps inclusion of such a definition would over-complicate a jury’s thought process and fail to give jury members credit for some rational thought process.
John J. Lapham, Criminal Law—Reasonable Doubt Definitional Instruction, 23 St. MaRy’s L.J. 1195, 1201 (1992).
The members of the average jury possess sufficient collective knowledge and common sense to be able to fairly and accurately apply the phrase without the benefit of a court’s definition. “The ‘reasonable doubt’ standard serves to prevent a finding of guilt unless the evidence dispels those doubts that would be entertained by that most useful construct of law — the reasonable person — in this instance, a group of twelve reasonable persons who form a reasonable jury.” Jon O. Newman, Beyond “Reasonable Doubt”, 68 N.Y.U. L.Rev. 979, 983 (1993).
Moreover, the reasonable doubt instruction is phrased in a way that would only confuse a jury that would otherwise be able to understand and apply the burden of proof. First, the Geesa definition uses the concept of hesitation in order to distinguish a reasonable doubt from all others in an internally contradictory manner. On one hand, the instruction states that a doubt is considered reasonable if it caused a reasonable person to “hesitate to act in the most important of his own affairs.” This effectively asks the jury to assess the reasonableness of the doubt by whether it would provoke them to inaction. But, as the Geesa court noted in the next paragraph, the jury is told to assess the reasonableness of the doubt by whether it would be sufficient to provoke them to action. The definition does so by instructing them that proof “beyond a reasonable doubt” must be so convincing that “you” would act upon it without hesitation in those same important personal affairs. This use of the concept of hesitation is dangerously ambiguous. What would a jury do if they encountered a doubt that caused them to hesitate to act? “Should they decline to convict because they have reached a point of hesitation, or should they simply hesitate, then ask themselves whether, in their own private matter, they would simply resolve the doubt in favor of action, and, if so, continue on to convict?” Id. at 983.
Secondly, the references in the Geesa instruction to the personal matters of the jurors in defining whether they would hesitate to act, or act without hesitation, stands the risk of trivializing the constitutional standard as well as the importance of the work which the jury is doing. In U.S. v. Noone, 913 F.2d 20, 28-29 (1st Cir.1990), cert. denied 500 U.S. 906, 111 S.Ct. 1686, 114 L.Ed.2d 81 (1991), the First Circuit Court of Appeals criticized an instruction which used the phrase “a matter of importance in his or her personal life.” “The momentous decision to acquit or convict a criminal defendant cannot be compared with ordinary decision-making without risking trivialization of the constitutional standard.... We admonish against the use of any such instruction, as an altogether unnecessary embellishment that risks juror misunderstanding of the reasonable doubt standard.” Id. It cannot be predicted what an individual juror might believe was the “most important of his or her own personal affairs,” especially when the Geesa instruction mandates that each of them conceive of what he or she believes is an important affair.
Lastly, I believe the wording of the Gee-sa instruction could confuse jurors into applying a reduced burden of proof on the State to prove its case. In the instruction, jurors are informed that a reasonable *577doubt is a “doubt based on reason.” “A juror hearing the ‘doubt based on reason’ formulation might think that a generalized unease or skepticism about the prosecution’s evidence is not a valid basis to resist entreaties to vote for conviction. This is probably a distortion of the concept the courts are seeking to implement. ... The standard ought not to mean that a doubt is reasonable only if the juror can articulate to himself or herself some particular reason for it.” Newman, supra at 988. The Geesa instruction confuses the concept of “proof beyond a reasonable doubt,” and it does not assist the trier of fact in the application of the burden of proof to the evidence at trial.
IV.
The constitutional standard of “proof beyond a reasonable doubt” needs no embellishment. For years, the standard conveyed to jurors the fact that they could not convict a fellow citizen without reaching the subjective state of near certitude of the guilt of that citizen. See id. at 984. The Supreme Court acknowledged in Victor v. Nebraska that a definition of reasonable doubt is not necessary under the Constitution. I believe the Geesa instruction is flawed by its own internal contradictions, confused phrasing and trivialization of the constitutional standard.
For the reasons set out above, I concur in the judgment of the majority.
MEYERS, J., delivered this dissenting opinion, joined by PRICE, J.
The majority overrules Geesa v. State, 820 S.W.2d 154 (Tex.Crim.App.1991), on the ground that it is “poorly reasoned.” This is an insufficient basis upon which to overrule precedent. Moreover, the majority’s criticism of Geesa is not convincing. I would decline the State’s invitation to overrule Geesa, but, in light of the Court’s irreconcilable opinion in Cain v. State, 947 S.W.2d 262 (Tex.Crim.App.1997), would overrule Reyes v. State, 938 S.W.2d 718 (Tex.Crim.App.1996) and disavow some of our language in State v. Toney, 979 S.W.2d 642 (Tex.Crim.App.1998).
I.
The majority overrules Geesa solely because it views Geesa as having been “poorly reasoned.” Majority opinion at 572. The United States Supreme Court recently indicated that disagreement with the reasoning of a prior opinion is not enough to justify overruling it:
Whether or not we would agree toith Miranda’s reascming and its resulting rule, were we addressing the issue in the first instance, the principles of stare decisis weigh heavily against overruling it now. While “ ‘stare decisis is not an inexorable command,’ ” particularly when we are interpreting the Constitution, “even in constitutional cases, the doctrine carries such persuasive force that we have always required a departure from precedent to be supported by some ‘special justification.’ ”
Dickerson v. United States, — U.S. —, 120 S.Ct. 2326, 147 L.Ed.2d 405 (2000) (emphasis added) (citations omitted). The “poorly reasoned” test stands in stark contrast to the “series of prudential and pragmatic considerations” the Supreme Court has said ought to be considered in overruling precedent:
whether the rule has proven to be intolerable simply in defying practical workability, ... whether the rule is subject to a kind of reliance that would lend a special hardship to the consequences of overruling and add inequity to the cost of repudiation, ... whether related principles of law have so far developed as to have left the old rule no more than a remnant of abandoned doctrine, ... or whether facts have so changed, or come to be seen so differently, as to have robbed the old rule of significant application or justification.
Planned Parenthood of Southeastern Pennsylvania v. Casey, 505 U.S. 833, 854, 112 S.Ct. 2791, 120 L.Ed.2d 674 (1992).
*578While the Court today makes no attempt to consider anything other than its own disagreement with Geesa ⅛ reasoning, this Court has previously viewed consistency in the law as one of the critical considerations on the question of overruling precedent:
Those interests [underlying the rule of stare decisis ] have much less force ... when the precedent itself fails to produce consistency. When older precedent conflicts with a newer decision that is found to be more soundly reasoned, we may resolve the inconsistency in favor of the more soundly reasoned decision. And, in determining whether to retain or reject a particular rule of law, we may consider whether justifications proffered for the rule have been undercut with the passage of time.
Awadelkariem v. State, 974 S.W.2d 721, 725 (Tex.Crim.App.1998) (citations omitted); see also Busby v. State, 990 S.W.2d 263, 267 (Tex.Crim.App.1999)(declining invitation to overrule precedent, court stated, “doctrine of stare decisis indicates a preference for maintaining consistency even if a particular precedent is wrong”), cert. denied, — U.S. —, 120 S.Ct. 803, 145 L.Ed.2d 676 (2000). Serious lack of practical workability of the established precedent, inconsistency with related developments in the law, and diminishing importance or viability in light of developing law are key considerations that ought all be considered in questioning precedent.
The prior court’s logic or reasoning-should be given little, if any, consideration. Casey does not even mention such factor. The problem with the “poorly reasoned” standard is that it allows for overruling precedent based upon nothing more than a change in the Court’s membership.1 Restated, the test is really, “would a current majority on the Court have voted for the prior opinion?” If not, it is “poorly reasoned” and may be overruled. This Court long ago recognized the threat to judicial integrity when the viability of precedent depends upon the personal viewpoint of the current court membership:
Where this court has held for a number of years to a given construction of the law, we feel bound thereby, and, if any change is to be made in the rule of decision adhered to for any great length of time, this is to be exercised by the legislative branch of the government, and not this court. We have folloived, and are now following, the decisions of this court in many instances where toe think it for the best interest of the state that the law was otherwise than as held by this court; yet, as we have heretofore said, the bar and the -people of this state are entitled to know what is the law, and that it should not be subject to change by the mere opinion of one who is fortunate enough to be elected to this high position. As said in the Lewis Case, [Lewis v. State, 58 Tex.Crim. 351,] 127 S.W. 808: “For the reasons given here, we feel that at this late date to sweep aside the established rule and unsettle the law still further would be, if not judicial usurpation, at least without sufficient warrant in law and utterly inexcusable, and to proclaim ourselves as unworthy to sit on this high tribunal. It should never be forgotten that this is a land where the law reigns supreme.” Uniformity and certainty of decision is of the highest importance. We are not so much to declare our personal views of ivhat the law ought to be, but to lay doum with as much definiteness and certainty as may be what it is, and, when so adjudged, to enforce it with inflexible fidelity, without passion, and without iveakness. If, coming to this high position of power and responsibility, I may, moved by a mere personal opinion, in my day and time, unsettle and undo the work of the great men who *579have preceded me, consistent, coherent, and undoubted from the day when I was yet a briefless lawyer, the man who on the morrow takes my place will have the same warrant to undo and unsettle the rules we establish, and so on to the end of time.
Morris v. State, 64 Tex.Cr.R. 498, 142 S.W. 876, 877 (1912) (emphasis added). This type of judicial conservatism is no longer in vogue.
Turning to what have traditionally been appropriate factors for consideration on the question of overruling precedent, Casey, supra; Awadelkariem, supra, none of these considerations weigh in favor of overruling Geesa. The required definition has not “proven to be intolerable simply in defying practical workability.” To the contrary, Geesa promotes consistency among the trial courts and circumvents conflict between the parties. Moreover, submission of a proper Geesa instruction precludes the possibility that the case would be reversed due to a constitutionally deficient definition.2 See Sullivan v. Louisiana, 508 U.S. 275, 282, 113 S.Ct. 2078, 124 L.Ed.2d 182 (1993)(constitutionally deficient reasonable-doubt definition given in jury charge is “structural error” and thus not amenable to harmless error analysis).
Neither does Geesa present an inconsistency with developing law. Thus, absent some indication that Geesa has presented a real problem in terms of practical application or some evidence that developing law is at irreconcilable odds with Geesa, it ought not be overruled.
Some of Geesa's lineage, however, is problematic enough to necessitate reconsideration. Casey, 505 U.S. at 854, 112 S.Ct. 2791 (“[t]he obligation to follow precedent begins with necessity, and a contrary necessity marks its outer limit”). Geesa itself did not speak to the issue of whether a harm analysis would be appropriate in the event of error thereunder. This issue was expressly addressed in Reyes, supra, which held that failure to comply with Geesa was not subject to a harm analysis. In Reyes, the Court reasoned that Geesa error is immune from a harm analysis because it viewed the Geesa instruction as an “absolute, systemic requirement.” We subsequently held in Cain, supra, that even error related to these types of features is not categorically immune from a harm analysis. Cain 947 S.W.2d at 264 (even jurisdictional errors are not categorically immune from harm analysis). The only type of error categorically immune from a harmless error analysis is federal constitutional error labeled as “structural” by the United States Supreme Court. Id. The Geesa instruction is not constitutionally required, and thus a failure to give such instruction does not by any stretch fall within this narrow class of errors. Reyes and Cain are at irreconcilable odds and cannot both be retained. I would overrule Reyes in light of Cain3
*580Further, Toney’s attempt to harmonize Geesa, Reyes and Cain, while a well-intentioned effort to preserve precedent, is not logically defensible. The Court’s statement in Toney that a complete failure to give a Geesa instruction is not subject to a harm analysis cannot be harmonized with Cain’s, directive that no error is immune from a harm analysis.4 I would disavow this statement and hold that Geesa error is charge error and, not being constitutional in nature, is subject to a harmless error analysis under Almanza v. State, 686 S.W.2d 157 (Tex.Crim.App.1984)(Op. on reh’g), cert. denied, 481 U.S. 1019, 107 S.Ct. 1901, 95 L.Ed.2d 507 (1987).
II.
The majority says Geesa is poorly reasoned because the definitional instruction is (1) “redundant, confusing and logically flawed” and “useless,” “ambiguous” and “fallacious” and (2) not constitutionally required. This is harsh criticism considering a good portion of the Geesa instruction is based upon the definitions recommended by at least five federal circuits.
The majority criticizes the following portion of the instruction as “useless”: “a reasonable doubt is a doubt based on reason and common sense after a careful and impartial consideration of all the evidence in the case.” According to the majority, this “is like saying ‘[a] white horse is a horse that is white.’ ” Majority opinion at 572. But a number of federal circuits incorporate this instruction into their recommended definitions. 1 Federal Jury Practice and Instructions § 12.10 at 363 (West 1992) (Pattern Jury Instructions of the District Judges Association of the Fifth Circuit, Criminal Cases, Instruction No. 1.06 (1990) stating, “A ‘reasonable doubt’ is a doubt based upon reason and common sense after careful and impartial consideration of all the evidence in the case”); id. at 365 (Pattern Jury Instructions of the District Judges Association of the Sixth Circuit, Instruction No. 1.03 (1991), stating “A reasonable doubt is a doubt based on reason and common sense”); id. at 369 (Manual of Model Criminal Jury Instructions for the District Courts of the Eighth Circuit, Instruction No. 3.11 (1992), stating, “A reasonable doubt is a doubt based upon reason and common sense, and not the mere possibility of innocence”); id. at 372 (Pattern Jury Instructions of the District Judges Association of the Eleventh Circuit, Criminal Cases, Basic Instruction No. 3 (1985), stating, “A ‘reasonable doubt’ is a real doubt, based upon reason and common sense after careful and impartial consideration of all the evidence in the case”); 1 Federal Jury Practice and Instructions § 12.10 at 81 (West Supp.l997)(Manual of Model Criminal Jury Instructions for the Ninth Circuit, Instruction No. 3.3 (1997), stating, “A reasonable doubt is a doubt based upon reason and common sense and is not based purely on speculation”). Because there are reasonable minds who do not view this instruction as “useless,” this is a perfect example of why the “poorly reasoned” test should not carry the day.
The majority dislikes the instruction’s following discussion of “hesitation”:
[A reasonable doubt] is the kind of doubt that would make a reasonable person hesitate to act in the most important of his own affairs.
Proof beyond a reasonable doubt, therefore, must be proof of such a convincing character that you would be will*581ing to rely and act upon it without hesitation in the most important of your own affairs.
The first portion of this instruction is similar to the preferred instruction of a number of federal courts. 1 Federal Jury Practice and Instructions § 12.10 at 86B (West 1992) (Pattern Jury Instructions of the District Judges Association of the Fifth Circuit, Criminal Cases, Instruction No. 1.06 (1990) stating, “Proof beyond a reasonable doubt, therefore, is proof of such a convincing character that you would be willing to rely and act upon it without hesitation in the most important of your own affairs”); id. at 365 (Pattern Jury Instructions of the District Judges Association of the Sixth Circuit, Instruction No. 1.03 (1991), stating “Proof beyond a reasonable doubt means proof which is so convincing that you would not hesitate to rely and act on it in making the most important decisions in your own lives”); id. at 369 (Manual of Model Criminal Jury Instructions for the District Courts of the Eighth Circuit, Instruction No. 3.11 (1992), stating, “A reasonable doubt is the kind of doubt that would make a reasonable person hesitate to act”); id. at 372 (Pattern Jury Instructions of the District Judges Association of the Eleventh Circuit, Criminal Cases, Basic Instruction No. 3 (1985), stating, “Proof beyond a reasonable doubt, therefore, is proof of such a convincing character that you would be willing to rely and act upon it without hesitation in the most important of your own affairs”).
The majority says the second “hesitation” instruction is a “fallacious application” of the previous “hesitation” instruction. Their only support for this criticism is to say that the instruction “is like saying, ‘Pneumonia makes you cough’; therefore, if you cough, you have pneumonia.” Majority opinion at 572. This illustration does not accurately parallel the definition and is not enough basis upon which to conclude the entire instruction ought to be thrown out.5
Finally, the majority suggests that a Supreme Court holding in 1994 that the Constitution neither requires nor prohibits defining reasonable doubt is inconsistent with Geesa, implying that Geesa rested on constitutional grounds. Majority opinion at 573. But Geesa recognized its rule was “not of constitutional dimension^ rather, it] serve[d] to implement the constitutional requirement that a criminal conviction cannot stand ‘except upon proof beyond a reasonable doubt.’ ” Geesa, 820 S.W.2d at 163.
If I had been on the Court at the time Geesa was decided, I might not have joined it. Or I might have. A judge’s personal affinity for precedent ought to be irrelevant.6 Today, personal dislike for precedent has become the standard for overruling it. I would reverse the Court
to act.... [W]e feel that, taken as a whole, the instructions correctly conveyed the concept of reasonable doubt to the jury.
*582of Appeals and remand to that Court to assess harm under Almanza. The majority reverses the Court of Appeals and affirms the trial court. For these reasons, I dissent.
PRICE, J., filed a dissenting opinion.
The Fourteenth Amendment’s Due Process Clause requires that trial judges instruct jurors that they can only convict a person on proof beyond a reasonable doubt.1 Today, a majority of this Court holds that trial judges need not define the term reasonable doubt for Texas jurors. Because the Court leaves jurors with no guidance as to the meaning of this critical standard, I dissent.
The majority seems to argue that Gee-sa2 should be overruled because (1) the definition is seriously flawed, and (2) the U.S. Constitution neither requires nor prohibits defining reasonable doubt.3 These reasons may justify rewriting the definition, but they do not justify disposing of a definition altogether.
The Supreme Court has neither prohibited nor required that juries receive a definition of the term reasonable doubt. As a result, state and federal courts are divided over whether a definition is required, prohibited, or voluntary.4 In Winship, the Supreme Court explained that the reasonable doubt standard “provides concrete substance for the presumption of innocence” 5 and “is the prime instrument for reducing the risk of convictions resting on factual error.”6 Just because the Supreme Court refuses to provide guidance, does not mean that we should abdicate our responsibility.
Twenty-one years after the Supreme Court decided Winship, we held that trial courts must define reasonable doubt in the jury charge.7 In Geesa, we held that a particular definition of reasonable doubt was required. Although this definition has been criticized,8 I would not hold, as the majority does, that no definition is required. Just because many lawyers can understand and articulate the concept of reasonable doubt, this does not mean that the average juror can understand and apply the concept. The definition is not meant for lawyers, trial judges, and appellate judges; the purpose of the instruction is to assist the jury in making its decision. If the definition does not do that, it should be rewritten.
The majority claims that “the better practice is to give no definition of reasonable doubt at all to the jury.”9 It provides no analysis for this proposition, but merely cites a law review note for this proposition. I think that more is required if we are to overrule Geesa ⅛ holding that a definition must be given.
The majority notes that the Geesa Court overruled more than one hundred years of precedent. This is true, but it is not surprising when one considers that the Supreme Court did not require that guilt be proved beyond a reasonable doubt until 1970. Presumably, the Geesa Court took this into consideration when overruling such longstanding precedent.
I will not join in a decision that equips Texas juries with a measuring stick but deprives them of the lines of demarcation *583that should guide them in measuring the evidence of guilt. I dissent.

. The trial court instructed the jury:
A reasonable doubt means a doubt that is based on reason and common sense. Such doubt must be substantial rather than speculative.

. Although Geesa was decided just nine years ago, only one judge who voted for the opinion remains on the Court today. Geesa, supra (authored by Maloney, J., joined by McCormick, P.J., White, Campbell, Miller, Over-street, Baird, and Benevides, J.J.. Clinton, J., dissented).
. In the absence of a pattern definition, trial courts, and ultimately appellate courts, will be faced time and again with substantial debate on endless varieties of definitions that may or may not be constitutionally acceptable. This debate carries substantial risk, given that a constitutionally deficient definition is "structural error” and automatically reversible.
. In holding that the Geesa instruction is an absolute, systemic requirement, the Court in Reyes pointed to the language in Geesa directing that the definition "shall” be submitted in "all” criminal cases, "even in the absence of an objection or request" by the parties. Reyes, 938 S.W.2d at 721. We further emphasized that the Geesa definition was fashioned to ensure proper implementation of the constitutional requirement that a conviction cannot stand without proof beyond a reasonable doubt, a requirement which is “so fundamental to the proper functioning of our adjudicatory process as to enjoy special protection in the system.” Id. n. 7 (quoting Marin, 851 S.W.2d at 278). While the constitutional requirement of proof beyond a reasonable doubt is a systemic and nonwaivable feature of our system, the explanation of what that standard means does not share the same status with the underlying constitutional principle. Admittedly, Geesa's directive that the definition be submitted in “all criminal cases” suggests that the instruction cannot be waived. However, the Court’s modification of that directive with the further explanation, “even in the *580absence of an objection or request” could be read as allowing room for the possibility of an express waiver.
Reyes was undoubtedly wrong in characterizing the Geesa instruction as an absolute, systemic requirement. It is more likely a right that is expressly waivable. A "waivable only” right is one that the trial judge has an independent duty to implement, even without a request.
. Toney would need not be overruled, as it was decided correctly on its facts, holding that the error in giving a partial Geesa instruction was subject to a harmless error analysis.
. While the Supreme Court has stated it does not view a definition of reasonable doubt as particularly helpful, it has approved the first "hesitation” explanation given in the Geesa instruction. Holland v. United States, 348 U.S. 121, 138, 75 S.Ct. 127, 99 L.Ed. 150 (1954). But even if one similar to the second "hesitation” explanation is given, it will not invalidate the instruction if the instruction taken as a whole nonetheless conveys the proper notion of reasonable doubt:
[The trial judge defined reasonable doubt] as "the kind of doubt ... which you folks in the more serious and important of your own lives might be willing to act upon.” We think this section of the charge should have been in terms of the kind of doubt that would make a person hesitate to act, rather than the kind on which he would be willing
