concurring in the result in No. 61, and dissenting in No. 582.
I regret not to be able to join the Court’s opinion. I cannot do so because I find lurking beneath its disarming generalizations a number of problems which not only leave me with serious misgivings as to the future effect of today’s decisions, but which also, in my view, call for different results in these two cases.
I.
My basic difficulties with the Court’s opinion are threefold. First, the opinion paints with such a broad brush that I fear it may result in a loosening of the tight reins which state and federal courts should hold upon the enforcement of obscenity statutes. Second, the Court fails to discriminate between the different factors which, in my opinion, are involved in the constitutional adjudication of state and federal obscenity cases. Third, relevant distinctions between the two obscenity statutes here involved, and the Court’s own definition of “obscenity,” are ignored.
In final analysis, the problem presented by these cases is how far, and on what terms, the state and federal governments have power to punish individuals for disseminating books considered to be undesirable because of their *497nature or supposed deleterious effect upon human conduct. Proceeding from the premise that “no issue is presented in either case, concerning the obscenity of the material involved,” the Court finds the “dispositive question” to be “whether obscenity is utterance within the area of protected speech and press,” and then holds that “obscenity” is not so protected because it is “utterly without redeeming social importance.” This sweeping formula appears to me to beg the very question before us. The Court seems to assume that “obscenity” is a peculiar genus of “speech and press,” which is as distinct, recognizable, and classifiable as poison ivy is among other plants. On this basis the constitutional question before us simply becomes, as the Court says, whether “obscenity,” as an abstraction, is protected by the First and Fourteenth Amendments, and the question whether a particular book may be suppressed becomes a mere matter of classification, of “fact,” to be entrusted to a fact-finder and insulated from independent constitutional judgment. But surely the problem cannot be solved in such a generalized fashion. Every communication has an individuality and “value” of its own. The suppression of a particular writing or other tangible form of expression is, therefore, an individual matter, and in the nature of things every such suppression raises an individual constitutional problem, in which a reviewing court must determine for itself whether the attacked expression is suppressable within constitutional standards. Since those standards do not readily lend themselves to generalized definitions, the constitutional problem in the last analysis becomes one of particularized judgments which appellate courts must make for themselves.
I do not think that reviewing courts can escape this responsibility by saying that the trier of the facts, be it a jury or a judge, has labeled the questioned matter as “obscene,” for, if “obscenity” is to be suppressed, the *498question whether a particular work is of that character involves not really an issue of fact but a question of constitutional judgment of the most sensitive and delicate kind. Many juries might find that Joyce's “Ulysses” or Bocaccio’s “Decameron” was obscene, and yet the conviction of a defendant for selling either book would raise, for me, the gravest constitutional problems, for no such verdict could convince me, without more, that these books are “utterly without redeeming social importance.” In short, I do not understand how the Court can resolve the constitutional problems now before it without making its own independent judgment upon the character of the material upon which these convictions were based. I am very much afraid that the broad manner in which the Court has decided these cases will tend to obscure the peculiar responsibilities resting on state and federal courts in this field and encourage them to rely on easy labeling and jury verdicts as a substitute for facing up to the tough individual problems of constitutional judgment involved in every obscenity case.
My second reason for dissatisfaction with the Court’s opinion is that the broad strides with which the Court has proceeded has led it to brush aside with perfunctory ease the vital constitutional considerations which, in my opinion, differentiate these two cases. It does not seem to matter to the Court that in one case we balance the power /of a State in this field against the restrictions of the Four- | teenth Amendment, and in the other the power of the j Federal Government against the limitations of the First \ Amendment. I deal with this subject more particularly later.
Thirdly, the Court has not been bothered by the fact that the two cases involve different statutes. In California the book must have a “tendency to deprave or corrupt its readers”; under the federal statute it must tend “to stir sexual impulses and lead to sexually impure *499thoughts.” 1 The two statutes do not seem to me to present the same problems. Yet the Court compounds confusion when it superimposes on these two statutory definitions a third, drawn from the American Law Institute’s Model Penal Code, Tentative Draft No. 6: “A thing is obscene if, considered as a whole, its predominant appeal is to prurient interest.” The bland assurance that this definition is the same as the ones with which we deal flies in the face of the authors’ express rejection of the “deprave and corrupt” and “sexual thoughts” tests:
“Obscenity [in the Tentative Draft] is defined in terms of material which appeals predominantly to prurient interest in sexual matters and which goes beyond customary freedom of expression in these matters. We reject the prevailing test of tendency to arouse lustful thoughts or desires because it is *500unrealistically broad for a society that plainly tolerates a great deal of erotic interest in literature, advertising, and art, and because regulation of thought or desire, unconnected with overt misbehavior, raises the most acute constitutional as well as practical difficulties. We likewise reject the common definition of obscene as that which ‘tends to corrupt or debase.’ If this means anything different from tendency to arouse lustful thought and desire, it suggests that change of character or actual misbehavior follows from contact with obscenity. Evidence of such consequences is lacking .... On the other hand, ‘appeal to prurient interest’ refers to qualities of the material itself: the capacity to attract individuals eager for a forbidden look . ...” 2
As this passage makes clear, there is a significant distinction between the definitions used in the prosecutions before us, and the American Law Institute formula. If, therefore, the latter is the correct standard, as my Brother Brennan elsewhere intimates,3 then these convictions should surely be reversed. Instead, the Court merely assimilates the various tests into one indiscriminate potpourri.
I now pass to the consideration of the two cases before us.
II.
1 concur in the judgment of the Court in No. 61, Alberts v. California.
The question in this case is whether the defendant was deprived of liberty without due process of law when he was convicted for selling certain materials found by the judge to be obscene because they would have a “tendency *501to deprave or corrupt its readers by exciting lascivious thoughts or arousing lustful desire.”
In judging the constitutionality of this conviction, we should remember that our function in reviewing state judgments under the Fourteenth Amendment is a narrow one. We do not decide whether the policy of the State is wise, or whether it is based on assumptions scientifically substantiated. We can inquire only whether the state action so subverts the fundamental liberties implicit in the Due Process Clause that it cannot be sustained as a rational exercise of power. See Jackson, J., dissenting in Beauharnais v. Illinois, 343 U. S. 250, 287. The States’ power to make printed words criminal is, of course, confined by the Fourteenth Amendment, but only insofar as such power is inconsistent with our concepts of “ordered liberty.” Palko v. Connecticut, 302 U. S. 319, 324-325.
What, then, is the purpose of this California statute? Clearly the state legislature has made the judgment that I printed words can “deprave or corrupt” the reader — that' words can incite to antisocial or immoral action. The assumption seems to be that the distribution of certain types of literature will induce criminal or immoral sexual conduct. It is well known, of course, that the validity of this assumption is a matter of dispute among critics, sociologists, psychiatrists, and penologists. There is a large school of thought, particularly in the scientific community, which denies any causal connection between the reading of pornography and immorality, crime, or delinquency. Others disagree. Clearly it is not our function to decide this question. That function belongs to the state legislature. Nothing in the Constitution requires California to accept as truth the most advanced and sophisticated psychiatric opinion. It seems to me clear that it is not irrational, in our present state of knowledge, to consider that pornography can induce a type of sexual conduct which a State may deem obnoxious to the *502moral fabric of society. In fact the very division of opinion on the subject counsels us to respect the choice made by the State.
Furthermore, even assuming that pornography cannot be deemed ever to cause, in an immediate sense, criminal sexual conduct, other interests within the proper cognizance of the States may be protected by the prohibition placed on such materials. The State can reasonably draw the inference that over a long period of time the indiscriminate dissemination of materials, the essential character of which is to degrade sex, will have an eroding effect on moral standards. And the State has a legitimate interest in protecting the privacy of the home against invasion of unsolicited obscenity.
Above all stands the realization that we deal here with an area where knowledge is small, data are insufficient, and experts are divided. Since the domain of sexual morality is pre-eminently a matter of state concern, this Court should be slow to interfere with state legislation calculated to protect that morality. It seems to me that nothing in the broad and flexible command of the Due Process Clause forbids California to prosecute one who sells books whose dominant tendency might be to “deprave or corrupt” a reader. I agree with the Court, of course, that the books must be judged as a whole and in relation to the normal adult reader.
What has been said, however, does not dispose of the case. It still remains for us to decide whether the state court’s determination that this material should be suppressed is consistent with the Fourteenth Amendment; and that, of course, presents a federal question as to which we, and not the state court, have the ultimate responsibility. And so, in the final analysis, I concur in the judgment because, upon an independent perusal of the material involved, and in light of the considerations dis*503cussed above, I cannot say that its suppression would so interfere with the communication of “ideas” in any proper sense of that term that it would offend the Due Process Clause. I therefore agree with the Court that appellant’s conviction must be affirmed.
III.
I dissent in No. 582, Roth v. United States.
We are faced here with the question whether the federal obscenity statute, as construed and applied in this case, violates the First Amendment to the Constitution. To me, this question is of quite a different order than one where we are dealing with state legislation under the Fourteenth Amendment. I do not think it follows that state and federal powers in this area are the same, and that just because the State may suppress a particular utterance, it is automatically permissible for the Federal Government to do the same. I agree with Mr. Justice Jackson that the historical evidence does not bear out the claim that the Fourteenth Amendment “incorporates” the First in any literal sense. See Beauharnais v. Illinois, supra. But laying aside any consequences which might flow from that conclusion, cf. Mr. Justice Holmes in Gitlow v. New York, 268 U. S. 652, 672,4 I prefer to rest my views about this case on broader and less abstract grounds.
The Constitution differentiates between those areas of human conduct subject to the regulation of the States and those subject to the powers of the Federal Government. The substantive powers of the two governments, in many *504instances, are distinct. And in every case where wé are called upon to balance the interest in free expression against other interests, it seems to me important that we should keep in the forefront the question of whether those other interests are state or federal. Since under our constitutional scheme the two are not necessarily equivalent, the balancing process must needs often produce different results. Whether a particular limitation on speech or press is to be upheld because it subserves a paramount governmental interest must, to a large extent, I think, depend on whether that government has, under the Constitution, a direct substantive interest, that is, the power to act, in the particular area involved.
The Federal Government has, for example, power to restrict seditious speech directed against it, because that Government certainly has the substantive authority to protect itself against revolution. Cf. Pennsylvania v. Nelson, 350 U. S. 497. But in dealing with obscenity we are faced with the converse situation, for the interests which obscenity statutes purportedly protect are primarily entrusted to the care, not of the Federal Government, but of the States. Congress has no substantive power over sexual morality. Such powers as the Federal Government, has in this field are but incidental to its other powers, here the postal power, and are not of the same nature as those possessed by the States, which bear direct responsibility for the protection of the local moral fabric.5 *505What Mr. Justice Jackson said in Beauharnais, supra, 343 U. S., at 294-295, about criminal libel is equally true of obscenity:
“The inappropriateness of a single standard for restricting State and Nation is indicated by the disparity between their functions and duties in relation to those freedoms. Criminality of defamation is predicated upon power either to protect the private right to enjoy integrity of reputation or the public right to tranquillity. Neither of these are objects of federal cognizance except when necessary to the accomplishment of some delegated power . . . . When the Federal Government puts liberty of press in one scale, it has a very limited duty to personal reputation or local tranquillity to weigh against it in the other. But state action affecting speech or press can and should be weighed against and reconciled with these conflicting social interests.”
Not only is the federal interest in protecting the Nation against pornography attenuated, but the dangers of federal censorship in this field are far greater than anything the States may do. It has often been said that one of the great strengths of our' federal system is that we have, in the forty-eight States, forty-eight experimental social laboratories. “State statutory law reflects predominantly this capacity of a legislature to introduce novel techniques of social control. The federal system has the immense advantage of providing forty-eight separate centers for such experimentation.” 6 Different States will have different attitudes toward the same work of literature. The same book which is freely read in one State might be *506classed as obscene in another.7 And it seems to me that no overwhelming danger to our freedom to experiment and to gratify our tastes in literature is likely to result from the suppression of a borderline book in one of the States, so long as there is no uniform nation-wide suppression of the book, and so long as other States are free to experiment with the same or bolder books.
Quite a different situation is presented, however, where the Federal Government imposes the ban. The danger is perhaps not great if the people of one State, through their legislature, decide that “Lady Chatterley’s Lover” goes so far beyond the acceptable standards of candor that it will be deemed offensive and non-sellable, for the State next door is still free to make its own choice. At least we do not have one uniform standard. But the dangers to free thought and expression are truly great if the Federal Government imposes a blanket ban over the Nation on such a book. The prerogative of the States to differ on their ideas of morality will be destroyed, the ability of States to experiment will be stunted. The fact that the people of one State cannot read some of the works of D. H. Lawrence seems to me, if not wise or desirable, at least acceptable. But that no person in the United States should be allowed to do so seems to me to be intolerable, and violative of both the letter and spirit of the First Amendment.
I judge this case, then, in view of what I think is the attenuated federal interest in this field, in view of the very real danger of a deadening uniformity which can result from nation-wide federal censorship, and in view of the *507fact that the constitutionality of this conviction must be weighed against the First and not the Fourteenth Amendment. So viewed, I do not think that this conviction can be upheld. The petitioner was convicted under a statute which, under the judge’s charge,8 makes it criminal to sell books which “tend to stir sexual impulses and lead to sexually impure thoughts.” I cannot agree that any book which tends to stir sexual impulses and lead to sexually impure thoughts necessarily is “utterly without redeeming social importance.” Not only did this charge fail to measure up to the standards which I understand the Court to approve, but as far as I can see, much of the great literature of the world could lead to conviction under such a view of the statute. Moreover, in no event do I think that the limited federal interest in this area can extend to mere “thoughts.” The Federal Government has no business, whether under the postal or commerce power, to bar the sale of books because they might lead to any kind of “thoughts.” 9
It is no answer to say, as the Court does, that obscenity is not protected speech. The point is that this statute, as here construed, defines obscenity so widely that it encompasses matters which might very well be protected speech. I do not think that the federal statute can be constitutionally construed to reach other than what the Government has termed as “hard-core” pornography. Nor do I think the statute can fairly be read as directed *508only at persons who are engaged in the business of catering to the prurient minded, even though their wares fall short of hard-core pornography. Such a statute would raise constitutional questions of a different order. That being so, and since in my opinion the material here involved cannot be said to be hard-core pornography, I would reverse this case with instructions to dismiss the indictment.
In Alberts v. California, the state definition of “obscenity” is, of course, binding on us. The definition there used derives from People v. Wepplo, 78 Cal. App. 2d Supp. 959, 178 P. 2d 853, the question being whether the material has “a substantive tendency to deprave or corrupt its readers by exciting lascivious thoughts or arousing lustful desire.”
In Roth v. United States, our grant of certiorari was limited to the question of the constitutionality of the statute, and did not encompass the correctness of the definition of “obscenity” adopted by the trial judge as a matter of statutory construction. We must therefore assume that the trial judge correctly defined that term, and deal with the constitutionality of the statute as construed and applied in this case.
The two definitions do not seem to me synonymous. Under the federal definition it is enough if the jury finds that the book as a whole leads to certain thoughts. In California, the further inference must be drawn that such thoughts will have a substantive “tendency to deprave or corrupt” — i. e., that the thoughts induced by the material will affect character and action. See American Law Institute, Model Penal Code, Tentative Draft No. 6, §207.10 (2), Comments, p. 10.

“The general principle of free speech, it seems to me, must be taken to be included in the Fourteenth Amendment, in view of the scope that has been given to the word ‘liberty’ as there used, although perhaps it may be accepted with a somewhat larger latitude of interpretation than is allowed to Congress by the sweeping language that governs or ought to govern the laws of the United States.”
The hoary dogma of Ex parte Jackson, 96 U. S. 727, and Public Clearing House v. Coyne, 194 U. S. 497, that the use of the mails is a privilege on which the Government may impose such conditions as it chooses, has long since evaporated. See Brandéis, J., dissenting, in Milwaukee Social Democratic Publishing Co. v. Burleson, 255 U. S. 407, 430-433; Holmes, J., dissenting, in Leach v. Carlile, 258 U. S. 138, 140; Cates v. Haderline, 342 U. S. 804, reversing 189 F. 2d 369; Door v. Donaldson, 90 U. S. App. D. C. 188, 195 F. 2d 764.

To give only a few examples: Edmund Wilson’s “Memoirs of Hecate County” was found obscene in New York, see Doubleday & Co. v. New York, 335 U. S. 848; a bookseller indicted for selling the same book was acquitted in California. “God’s Little Acre” was held to be obscene in Massachusetts, not obscene in New York and Pennsylvania.
While the correctness of the judge’s charge is not before us, the question is necessarily subsumed in the broader question involving the constitutionality of the statute as applied in this case.
See American Law Institute, Model Penal Code, Tentative Draft No. 6, § 207.10, Comments, p. 20: “As an independent goal of penal legislation, repression of sexual thoughts and desires is hard to support. Thoughts and desires not manifested in overt antisocial behavior are generally regarded as the exclusive concern of the individual and his spiritual advisors.”
