Egoism was the first journal explicitly based on Egoist ideas in the English language, and was published by individualist anarchists Georgia and Henry Replogle beginning in 1890. An advertisement from the period stated:

"Its purpose is the improvement of social existence from the standpoint of intelligent self-interest. To gain recognition of the fact, and popularize the idea, that self-pleasure can be the only motive of any act; that any attempt to ignore it must as necessarily be disastrous to human happiness as an attempt to ignore any part of the order of nature. Thus developing a principle for a basis of action about which there can be no misunderstanding, and which will place every person squarely on the merit of his or her probable interests, divested of the opportunity to deceive through pretension, as under the dominance of altruistic idealism. From this basis Egoism will defend the individual against every phase of invasion, whether it be the exactions of political-authority-protected privilege or the decrees of superstition-influenced custom."

In the late 19th Century a pocket of America was ready for an expression of "rugged individualism" to transform into a more coherent worldview. The greatest articulation of that sprang from German philosopher Max Stirner's 1844 book Der Einzige und sein Eigenthum. This book serves foundation of Egoism, which is a philosophy of putting the self in the central concern, rather than gods, other men, "mankind" in the abstract. Though relatively unknown compared to other flag-bearers of free thinking individualism like Friedrich Nietzsche, Robert Ingersoll, Ayn Rand and others, the message of Stirner's book has had a critical impact on many writers and artists who were influential in Europe and America.
Stirner's great work (published in New York in 1907 as The Ego and His Own), while having no explicit connection to Anarchism, was championed early on by that milieu. First in Germany by John Henry Mackay, who saved Stirner from the dustbins, to writers and radicals in Russia, France, Spain and England.
Here in America, Egoism's first champions were Georgia and Henry P. Replogle, and British born James L. Walker (aka "Tak Kak"). Contemporaries with publishers Benjamin Tucker (Liberty), Moses Harman (Lucifer the Lightbearer), D. M. Bennett (Truth Seeker) and other radicals, the Replogle's are not as well known as their more prolific comrades.
The Egoism journal is most notable for first serializing Walker's The Philosophy of Egoism book, but it also contained writings from and about the anarchist and individualist discussion of the day. While Walker's book would later be reprinted as a single volume in 1905, issues of the journal itself became scarce and near impossible to access. The journal is important for historians of Anarchism, Individualism and Egoism; three ideas that overlap greatly, but often depart in fascinating ways.

"Anyone interested in (individualist anarchism of 19th century) should welcome any chance to examine the outlets edited by figures with different sensibilities. So it's good to see Georgia and Henry Replogle's journal Egoism reprinted in a hefty new book, Egoism: The First Two Volumes, 1890-1892. In some ways (Benjamin R.) Tucker and the Replogles were peas in a pod: Each mixed the radical egoism of Max Stirner with the monetary schemes of Pierre-Joseph Proudhon. But there are differences here too, with Egoism putting a stronger stress on feminism and free love." -Jesse Walker, Reason Magazine
