Max Stirner
Max Stirner's attacks on systematic philosophy, his denial of absolutes, and his rejection of abstract concepts of any kind often places him among the first philosophical nihilists. For Stirner, achieving individual freedom is the only law; and the state, which necessarily imperils freedom, must be destroyed. Even beyond the oppression of the state, though, are the constraints imposed by others because their very existence is an obstable compromising individual freedom. Thus Stirner argues that existence is an endless "war of each against all" (1845). (taken from the paragraph about Max Stirner in Nihilism)
Sourcing here? Much complexity in properly understanding Stirner, who has some Pynchon-like qualities, to say the least.
His major work: The Ego and Its Own
Much of Stirner's prose — which is crowded with aphorisms, italicization, and hyperbole — appears calculated to disconcert. Most striking, perhaps, is the use of wordplay. Rather than reach a conclusion through the conventional use of argument, Stirner often approaches a claim that he wishes to endorse by exploiting words with related etymologies or formal similarities. For example, he associates words for property (such as ‘Eigentum’) with words connoting distinctive individual characteristics (such as ‘Eigenheit’) in order to promote the claim that property is expressive of selfhood. (Stirner's account of egoistic property—see below—gives this apparently orthodox Hegelian claim a distinctive twist.)
This rejection of conventional forms of intellectual discussion is linked to Stirner's substantive views about language and rationality. His unusual style reflects a conviction that both language and rationality are human products which have come to constrain and oppress their creators. Stirner maintains that accepted meanings and traditional standards of argumentation are underpinned by a conception of truth as a privileged realm beyond individual control. As a result, individuals who accept this conception are abandoning a potential area of creative self-expression in favour of adopting a subordinate role as servants of truth. In stark contrast, Stirner insists that the only legitimate restriction on the form of our language, or on the structure of our arguments, is that they should serve our individual ends. It is the frequent failure of ordinary meanings and standard forms of argument to satisfy his interpretation of this criterion which underpins Stirner's remorselessly idiosyncratic style.
The Ego and Its Own has an intelligible, but scarcely transparent, structure. It is organized around a tripartite account of human experience, initially introduced in a description of the stages of an individual life. The first stage in this developmental narrative is the realistic one of childhood, in which children are constrained by material and natural forces such as their parents. Liberation from these external constraints is achieved with what Stirner calls the self-discovery of mind, as children find the means to outwit those forces in their own determination and cunning. The idealistic stage of youth, however, contains new internal sources of constraint, as individuals once more become enslaved, this time to the spiritual forces of conscience and reason. Only with the adulthood of egoism do individuals escape both material (external) and spiritual (internal) constraints, learning to value their personal satisfaction above all other considerations.
Stirner portrays this dialectic of individual growth as an analogue of historical development, and it is a tripartite account of the latter which structures the remainder of the book. Human history is reduced to successive epochs of realism (the ancient, or pre-Christian, world), idealism (the modern, or Christian, world), and egoism (the future world).
What about these "successive epochs" in understanding ATD?
The Ego and Its Own has been reissued in English a number of times in Pynchon's lifetime, from the 60s on. (Not that TRP could not have read it in German!)
