concurring.

The case lies within very narrow confines. The publication under scrutiny is a periodical. It is therefore entitled to the special rates accorded by Congress provided it is published “for the dissemination of information of a public character, or devoted to literature, the sciences, arts . . .” If it be devoted to “literature” it becomes unnecessary to consider how small an infusion of “information of a public character” entitles a periodical to the second-class mail rates when the bulk of its contents would not otherwise satisfy the Congressional conditions.

Congress has neither defined its conception of “literature” nor has it authorized the Postmaster General to do so. But it has placed a limitation upon what is to be deemed “literature” for a privilege which the Court rightly calls a form of subsidy. Matters that are declared nonmailable (Criminal Code § 211; 35 Stat. 1129,36 Stat. 1339; 18 U. S. C. § 334) are of course not “literature” within the scope of the second-class privilege. But the Postmaster General does not contend that the periodical with which we are concerned was nonmailable. He merely contends that it was not devoted to the kind of “literature” or “art” which may claim the subsidy of second-class matter. But since Congress has seen fit to allow “literature” conveyed by periodicals to have the second-class privilege without making any allowable classification of “literature,” except only that nonmailable matter as defined by § 211 of the Criminal Code is excluded, the *160area of “literature, the sciences, arts” includes all composition of words, pictorial representation,' or notations that are intelligible to any portion of the population, no matter whether their appeal is extensive or esoteric. Since the Postmaster General disavows the nonmailability of the issues of the periodical he had before him and since Congress did not qualify “literature, the sciences, arts” by any standards of taste or edification or public elevation, the Postmaster General exceeded his powers in denying this periodical a second-class permit.

It seems to me important strictly to confine discussion in this case because its radiations touch, on the one hand, the very basis of a free society, that of the right of expression beyond the conventions of the day,, and, on the other hand, the freedom of society from constitutional compulsion to subsidize enterprise, whether in the world of matter or of mind. While one may entirely agree with Mr. Justice Holmes, in Leach v. Carlile, 258 U. S. 138, 140, as to the extent to which the First Amendment forbids control of the post so far as sealed letters are concerned, one confronts an entirely different set of questions in considering the basis on which the Government may. grant or withheld subsidies through low postal rates, and huge subsidies, if one is to judge by the glimpse afforded by the present case. It will be time enough to consider such questions when the Court cannot escape decision upon them.

delivered the opinion of the Court.

Congress has made obscene material nonmailable (35 Stat. 1129, 18 U. S. C. § 334), and has applied criminal . sanctions for the enforcement of that policy. It has *148divided mstilable matter into four classes, periodical publications constituting the second-class.1 § 7 of the Classification Act of 1879, 20 Stat. 358, 43 Stat. 1067, 39 U. S. C. § 221. And it has specified four conditions upon which- a publication shall be admitted to the second-class. § 14 of the Classification Act of 1879,20 Stat. 359,48 Stat. 928, 39 U. S. C. § 226. The Fourth condition, which is the only one relevant here,2 provides:

“Except as otherwise provided by law, the conditions upon which a publication shall be admitted to the second class are as follows . . . Fourth. It must be originated and published for the dissemination of information of .a public character, or devoted to literature, the sciences, arts, or some special industry, and having a legitimate list of subscribers. Nothing herein contained shall be so construed as to admit to the second-class rate regular publications designed primarily for advertising purposes, or for free circulation, or for circulation at nominal rates.”

Respondent is the publisher of Esquire Magazine, a monthly periodical which was granted a second-class permit in 1933. In 1943, pursuant to the Act of March 3, -Í901, 31 Stat. 1107, 39 U. S. C. § 232, a citation was issued *149to respondent by the then Postmaster General (for whom the present Postmaster General has now been substituted as petitioner) to show cause why that permit should not be suspended or revoked.8 A hearing was held before a hoard designated by the then Postmaster General.3 4 The board recommended that the permit not be revoked. Petitioner’s predecessor took a different view. He did not find that Esqüire Magazine contained obscene material and therefore was nonmailable. He revoked its second-class permit because he found that it did not comply with the Fourth condition. The gist of his holding is contained in the following excerpt from his opinion:

“The plain language of this statute does not assume that a publication must in fact be ‘obscene’ within the intendment of the postal obscenity statutes before it can be found not to be ‘originated and published for the dissemination of information óf a public character, or devoted to literature, the sciences, arts, or' some special industry.’

“Writings and pictures may be indecent, vulgar, and risque and still not be obscene in a technical sense. Such writings and pictures may be in that obscure and treacherous borderland zone where the average person hesitates to find them technically obscene, but still may see ample proof that they are morally im- ■ proper and not for the public welfare and the public good. When such writings or pictures occur in isolated instances their dangerous tendencies and malignant qualities may be considered of lesser importance.

“When, however, they become a dominant and systematic feature they most certainly cannot be said to be for the public good, and a publication which uses them in that manner is not making the ‘special con*150tribution to the public welfare’ which Congress intended by the Fourth condition.

“A publication to enjoy these unique mail privir leges and special preferences is bound to do more than refrain from disseminating material which is obscene or bordering on the obscene. It is under a positive duty to contribute to the public good and the public welfare.”

Respondent thereupon sued in the District Court for the District of Columbia to enjoin the revocation order. The parties stipulated at a pre-trial conference that the suit would not be defended on the ground that Esquire Magazine was obscene or was for any other reason non-mailable.* 5 The district court denied the injunction and dismissed the complaint. 55 F. Supp. 1015. The court of appeals reversed. 151 F. 2d 49. The case is here on a petition for a writ of certiorari which we granted because of the importance of the problem in the administration of the postal laws.

The issues of Esquire Magazine under attack are those for January to November, inclusive, of 1943. The material complained of embraces in bulk only a small percentage of those issues.6 Regular features of the magazine (called “The Magazine for Men”) include articles on topics of current interest, short stories, sports articles or stories, short articles by men prominent in various fields of activities, articles about men prominent in the news, a book review department headed by the late William Lyon Phelps, a theatrical department headed by George Jean Nathan, a department on the lively arts by Gilbert Seldes, a department devoted to men’s clothing, and pictorial features,- including war action paintings, color photographs of dogs and water colors or etchings of game *151birds and reproductions of famous paintings, prints and drawings. There was very little in these features which was challenged. But petitioner’s predecessor found that the objectionable items, though a small percentage of the total bulk, were regular recurrent features which gave the magazine its dominant tone or characteristic. These include jokes, cartoons, pictures, articles, and poems. They were said to'reflect the smoking-room type of humor, featuring, in the main, sex. Some witnesses found the challenged items highly objectionable, calling them salacious and indecent. Others thought they were only racy and risque. Some condemned them as being merely in poor taste. Other witnesses could find no objection to them.

An examination of the items makes plain, we think, that the controversy is not whether the magazine publishes “information of a public character” or is devoted to “literature” op to the “arts.” It is whether the contents are “good” or “bad.” To uphold the order of revocation would, therefore, grant the Postmaster General a power of censorship. Such a power is so abhorrent to our traditions that a purpose to grant it should not be easily inferred.

The second-class privilege is a form of subsidy.7 From the beginning Congress has allowed special rates to certain classes of publications. The Act of February 20, 1792, 1 Stat. 232, 238, granted newspapers a more favorable rate. These were extended to magazines and pamphlets by tiie Act of May 8, 1794, 1 Stat. 354, 362. Prior to the Classification Act of 1879, periodicals were put into the second-class,8 which by the Act of March 3, 1863, 12 Stat. *152701, 705, included “all mailable matter exclusively in print, and regularly issued at stated periods, without addition by writing, mark, or sign.” That Act plainly adopted a strictly objective test and left no discretion to the postal authorities to withhold the second-class privilege from a mailable newspaper or periodical because it failed to meet some standard of worth or value or propriety. There is nothing in the language or history of the Classification Act of 1879 which suggests that Congress in that law made any basic change in its treatment of second-class mail, let alone such an abrupt and radical change as would be entailed by the inauguration of even a limited form of censorship.

The postal laws máke a clear-cut division between mailable and nonmailable material. The four classes of mailable matter are generally described by objective standards which refer in part to their contents, but not to the quality of their contents.9 The more particular descriptions of the first,10 third,* 11 and fourth12 classes follow the same *153pattern, as do the first three conditions specified for second-class matter.13 If, therefore, the Fourth condition is read in the context of the postal laws of which it is an integral part, it, too, must be taken to supply standards which relate to the format of the publication and to the nature of its contents, but not to their quality, worth, or value. In that view, “literature” or the “arts” mean no more than productions which convey ideas by words, pictures, or drawings.

If the Fourth condition is read in that way, it is plain that Congress made no radical or basic change in the type of regulation which it adopted for second-class mail in 1879. The inauguration of even a limited type of censorship would have been such a startling change as to have left some traces in the legislative history. But we find none. Congressman Money, a member of the Postal Committee who defended the bill on the floor of the House, stated that it was “nothing but a simplification of the postal code. There are no new powers granted to the Department by this bill, none whatever.” 8 Cong. Rec. 2134. The bill contained registration provisions which were opposed on the ground that they might be the inception of a censorship of the press. Id., p. 2137. These were deleted. Id., pp. 2137, 2138. It is difficult to imagine that the Congress, having deleted them for fear of censorship, gave the Postmaster General by the Fourth *154condition discretion to deny periodicals the second-class rate, if in his view they did not contribute to the public good. Congressman Money indeed referred to “the daily newspapers, with their load of gossip and scandal and every-day topics that are floating through the press”' as being entitled without question to the second-class privilege. Id., p. 2135, To the charge that", the bill imposed a censorship, he pointed out that it only withheld the privileged rate from publications “made up simply of advertising concerns not intended for public education”; and added:

“We know the reason for which papers are allowed to go at a low rate of postage, amounting almost' to the franking privilege, is because they are the most efficient educators of our people. It is because they go into general circulation and are intended for the dissemination of useful knowledge such as will promote the prosperity and the best interests of the people all over the country. Then all this vast mass of matter is excluded from that low rate of postage. I say, instead of being a censorship upon the press, it is for the protection of the legitimate journals of the country.” Id., p. 2135.

The policy of Congress has been clear. It has been to encourage the distribution of periodicals which disseminated “information of a public character” or which were devoted to “literature, the sciences, arts, or some special industry,” because it was thought that those publications as a class contributed to the public good.14 The standards prescribed in the Fourth condition have been criticized, but not on the ground that they provide for censorship.15 As stated by the Postal Commission of 1911, H. Doc. 559, 62d Cong., 2d Sess., p. 142:

*155“The original object in placing on second-class matter a rate far below that on any other class of mail was to encourage the dissemination of news and of current literature of educational value. This object has been only in part attained. The low rate has helped to stimulate an enormous mass of periodicals, many of which are of little utility for the cause of popular education. Others are of excellent quality, but the experience of the post office has shown the impossibility of making a satisfactory test based upon literary or educational values. To attempt to do so would be to set up a censorship of the press. Of necessity the words of the statute — ‘devoted to literature, the sciences, arts, or some special industry' — ‘ must have a broad interpretation.”

We may assume that Congress has a broad' power of classification and need not open second-class mail to publications of all types. The categories of publications entitled to that classification have indeed varied through the years.16 And the Court held in Ex parte Jackson, 96 U. S. 727, that Congress could constitutionally make it a *156crime to send fraudulent or obscene material through the mails. But grave constitutional questions are immediately raised once it is said that the use of the mails is a privilege which may be extended or withheld on any grounds whatsoever. See the dissents of Mr. Justice Brandeis and Mr. Justice Holmes in Milwaukee Publishing Co. v. Burleson, 255 U. S. 407, 421-423, 430-432, 437438. Under that view the second-class rate could be granted on condition that certain economic or political ideas not be disseminated. The provisions of the Fourth condition would have to be far more explicit for us to. assume that Congress made such a radical departure from our traditions17 and undertook to clothe the Postmaster General with the power to supervise the tastes of the reading public of the country'18

*157It is plain, as we have said, that the favorable second-class rates were granted periodicals meeting the requirements of the Fourth condition, so that the public good might be served through a dissemination of the class of periodicals described. But that is a far cry from assuming that Congress had any idea that each applicant for the second-class rate must convince the Postmaster General' that his publication positively contributes to the public good or public welfare. Under our system of government there is an accommodation for the widest varieties of tastes and ideaj.19 What is good literature, what has educational value, whát is refined public information, what is good art, varies with individuals as it does from one generation to another. There doubtless would be a contrariety of views20 concerning Cervantes’ Don Quixote, *158Shakespeare’s Venus and Adonis, or Zola’s Nana. But a requirement that literature or art conform to some norm prescribed by an official smacks of an ideology foreign to our system. The basic values implicit in the requirements of the Fourth condition can be served only by uncensored distribution of literature. From the multitude of competing offerings the public will pick and choose. What seems to one to be trash may have for others fleeting or even enduring values. But to withdraw the second-class rate from this publication today because its contents seemed to one official not good for the public would sanction withdrawal of the second-class rate tomorrow from another periodical whose social or economic views seemed harmful to another official. The validity of the obscenity laws is recognition that the mails may not be used to satisfy all tastes, no matter how perverted. But Congress has left the Postmaster'General with no power to prescribe standards for the literature or the art which a mailable periodical disseminates.

This is not to say that there is nothing left to the Postmaster General under the Fourth condition. It is his duty to “execute all laws relative to the Postal Service.” Rev. Stat. § 396, 5 U. S. C. § 369. For example, questions will arise as they did in Houghton v. Payne, 194 U. S. 88; Bates & Guild Co. v. Payne, 194 U. S. 106, and Smith v. Hitchcock, 226 U. S. 53, whether the publication which seeks the favorable second-class rate is a periodical as defined in the Fourth condition or a book or other type of publication. And it may appear that the information contained in a periodical may not be of a “public character.” But the power to determine whether a periodical (which is mailable) contains information of a public character, literature or art does not include the further power *159to determine whether the contents meet some standard of the public good or welfare.
