“[If] we can experimentally isolate a process and show that it can still work well, then it cannot require complex interaction with other parts of vision and can therefore be understood relatively well on its own.”
Vision, 1982

Letter to Thomas Law (13 June 1814)
1810s
Context: Self-interest, or rather self-love, or egoism, has been more plausibly substituted as the basis of morality. But I consider our relations with others as constituting the boundaries of morality. With ourselves, we stand on the ground of identity, not of relation, which last, requiring two subjects, excludes self-love confined to a single one. To ourselves, in strict language, we can owe no duties, obligation requiring also two parties. Self-love, therefore, is no part of morality. Indeed, it is exactly its counterpart.

Semiotics and the Philosophy of Language (1984)
Context: A philosophy does not play its role as an actor during a recital; it interacts with other philosophies and with other facts, and it cannot know the results of the interaction between itself and other world visions. World visions can conceive of everything, except alternative world visions, if not in order to criticize them and to show their inconsistency. Affected as they are by a constitutive solipsism, philosophies can say everything about the world they design and very little about the world they help to construct.
