“Dialectical egoism” names the movement by which the individual claims itself against the world’s claims while remaining engaged with the world. It is neither retreat nor domination; it is the appropriation of circumstances into meaning through responsible freedom. The dialectic is double: I negate the idols that demand my allegiance, and I affirm the projects that express my authenticity. No social cause, no scientific theory, no institutional voice is granted veto power over my responsibility. This is not anarchic license; it is disciplined self-possession.
