It is not however necessary, in order to sustain the view that the common law recognizes and upholds a principle applicable to cases of invasion of privacy, to invoke the analogy, which is but superficial, to injuries sustained, either by an attack upon reputation or by what the civilians called a violation of honor; for the legal doctrines relating to infractions of what is ordinarily termed the common-law right to intellectual and artistic property are, it is believed, but instances and applications of a general right to privacy, which properly understood afford a remedy for the evils under consideration.
The common law secures to each individual the right of determining, ordinarily, to what extent his thoughts, sentiments, and emotions shall be communicated to others.16 Under our system of government, he can never be compelled to express them (except when upon the witness-stand); and even if he has chosen to give them expression, he generally retains the power to fix the limits of the publicity which shall be given them. The existence of this right does not depend upon the particular method of expression adopted. It is immaterial whether it be by word17 or by signs,18 in painting,19 by sculpture, or in music.20 Neither does the existence of the right depend upon the nature or value of the thought or emotion, nor upon the excellence of the means of expression.21 The same protection is accorded to a casual letter or an entry in a diary and to the most valuable poem or essay, to a botch or daub and to a masterpiece. In every such case the individual is entitled to decide whether that which is his shall be given to the public.22 No other has the right to publish his productions in any form, without his consent. This right is wholly independent of the material on which, or the means by which, the thought, sentiment, or emotion is expressed. It may exist independently of any corporeal being, as in words spoken, a song sung, a drama acted. Or if expressed on any material, as a poem in writing, the author may have parted with the paper, without forfeiting any proprietary right in the composition itself. The right is lost only when the author himself communicates his production to the public, – in other words, publishes it.23 It is entirely independent of the copyright laws, and their extension into the domain of art. The aim of those statutes is to secure to the author, composer, or artist the entire profits arising from publication; but the common-law protection enables him to control absolutely the act of publication, and in the exercise of his own discretion, to decide whether there shall be any publication at all.24 The statutory right is of no value, unless there is a publication; the common-law right is lost as soon as there is a publication.
What is the nature, the basis, of this right to prevent the publication of manuscripts or works of art? It is stated to be the enforcement of a right of property;25 and no difficulty arises in accepting this view, so long as we have only to deal with the reproduction of literary and artistic compositions. They certainly possess many of the attributes of ordinary property: they are transferable; they have a value; and publication or reproduction is a use by which that value is realized. But where the value of the production is found not in the right to take the profits arising from publication, but in the peace of mind or the relief afforded by the ability to prevent any publication at all, it is difficult to regard the right as one of property, in the common acceptation of that term. A man records in a letter to his son, or in his diary, that he did not dine with his wife on a certain day. No one into whose hands those papers fall could publish them to the world, even if possession of the documents had been obtained rightfully; and the prohibition would not be confined to the publication of a copy of the letter itself, or of the diary entry; the restraint extends also to a publication of the contents. What is the thing which is protected? Surely, not the intellectual act of recording the fact that the husband did not dine with his wife, but that fact itself. It is not the intellectual product, but the domestic occurrence. A man writes a dozen letters to different people. No person would be permitted to publish a list of the letters written. If the letters or the contents of the diary were protected as literary compositions, the scope of the protection afforded should be the same secured to a published writing under the copyright law. But the copyright law would not prevent an enumeration of the letters, or the publication of some of the facts contained therein. The copyright of a series of paintings or etchings would prevent a reproduction of the paintings as pictures; but it would not prevent a publication of a list or even a description of them.26 Yet in the famous case of Prince Albert v. Strange, the court held that the common-law rule prohibited not merely the reproduction of the etchings which the plaintiff and Queen Victoria had made for their own pleasure, but also "the publishing (at least by printing or writing), though not by copy or resemblance, a description of them, whether more or less limited or summary, whether in the form of a catalogue or otherwise."27 Likewise, an unpublished collection of news possessing no element of a literary nature is protected from piracy.28
That this protection cannot rest upon the right to literary or artistic property in any exact sense, appears the more clearly when the subject-matter for which protection is invoked is not even in the form of intellectual property, but has the attributes of ordinary tangible property. Suppose a man has a collection of gems or curiosities which he keeps private: it would hardly be contended that any person could publish a catalogue of them, and yet the articles enumerated are certainly not intellectual property in the legal sense, any more than a collection of stoves or of chairs.29
The belief that the idea of property in its narrow sense was the basis of the protection of unpublished manuscripts led an able court to refuse, in several cases, injunctions against the publication of private letters, on the ground that "letters not possessing the attributes of literary compositions are not property entitled to protection;" and that it was "evident the plaintiff could not have considered the letters as of any value whatever as literary productions, for a letter cannot be considered of value to the author which he never would consent to have published."30 But these decisions have not been followed,31 and it may now be considered settled that the protection afforded by the common law to the author of any writing is entirely independent of its pecuniary value, its intrinsic merits, or of any intention to publish the same, and, of course, also, wholly independent of the material, if any, upon which, or the mode in which, the thought or sentiment was expressed.
Although the courts have asserted that they rested their decisions on the narrow grounds of protection to property, yet there are recognitions of a more liberal doctrine. Thus in the case of Prince Albert v. Strange, already referred to, the opinions both of the Vice-Chancellor and of the Lord Chancellor, on appeal, show a more or less clearly defined perception of a principle broader than those which were mainly discussed, and on which they both placed their chief reliance. Vice-Chancellor Knight Bruce referred to publishing of a man that he had "written to particular persons or on particular subjects" as an instance of possibly injurious disclosures as to private matters, that the courts would in a proper case prevent; yet it is difficult to perceive how, in such a case, any right of property, in the narrow sense, would be drawn in question, or why, if such a publication would be restrained when it threatened to expose the victim not merely to sarcasm, but to ruin, it should not equally be enjoined, if it threatened to embitter his life. To deprive a man of the potential profits to be realized by publishing a catalogue of his gems cannot per se be a wrong to him. The possibility of future profits is not a right of property which the law ordinarily recognizes; it must, therefore, be an infraction of other rights which constitutes the wrongful act, and that infraction is equally wrongful, whether its results are to forestall the profits that the individual himself might secure by giving the matter a publicity obnoxious to him, or to gain an advantage at the expense of his mental pain and suffering. If the fiction of property in a narrow sense must be preserved, it is still true that the end accomplished by the gossip-monger is attained by the use of that which is another's, the facts relating to his private life, which he has seen fit to keep private. Lord Cottenham stated that a man "is entitled to be protected in the exclusive use and enjoyment of that which is exclusively his," and cited with approval the opinion of Lord Eldon, as reported in a manuscript note of the case of Wyatt v. Wilson, in 1820, respecting an engraving of George the Third during his illness, to the effect that "if one of the late king's physicians had kept a diary of what he heard and saw, the court would not, in the king's lifetime, have permitted him to print and publish it;" and Lord Cottenham declared, in respect to the acts of the defendants in the case before him, that "privacy is the right invaded." But if privacy is once recognized as a right entitled to legal protection, the interposition of the courts cannot depend on the particular nature of the injuries resulting.
