4 ideas

1. Philosophy / C. History of Philosophy / 4. Later European Philosophy / d. Nineteenth century philosophy
Since Kant, self-criticism has been part of philosophy [Gutting]
     Full Idea: Philosophy after Kant has involved a continuing critique of its own project.
     From: Gary Gutting (Foucault: a very short introduction [2005], 6)
     A reaction: I'm struck by many modern philosophers in the analytic tradition who write as if Kant had never existed. I don't know if that is a conscious decision, but it may be a good one.
1. Philosophy / H. Continental Philosophy / 4. Linguistic Structuralism
Structuralism describes human phenomena in terms of unconscious structures [Gutting]
     Full Idea: Structuralism in the 1960s was a set of theories which explained human phenomena in terms of underlying unconscious structures, rather than the lived experience described by Phenomenology.
     From: Gary Gutting (Foucault: a very short introduction [2005], 6)
     A reaction: Hence the interest in Freud and Marx, and Foucault's interest in history, each offering to unmask what is hidden in consciousness. The unmasking is a basically Kantian project. Cf. Frege's hatred of 'psychologism'.
5. Theory of Logic / F. Referring in Logic / 1. Naming / e. Empty names
Unreflectively, we all assume there are nonexistents, and we can refer to them [Reimer]
     Full Idea: As speakers of the language, we unreflectively assume that there are nonexistents, and that reference to them is possible.
     From: Marga Reimer (The Problem of Empty Names [2001], p.499), quoted by Sarah Sawyer - Empty Names 4
     A reaction: Sarah Swoyer quotes this as a good solution to the problem of empty names, and I like it. It introduces a two-tier picture of our understanding of the world, as 'unreflective' and 'reflective', but that seems good. We accept numbers 'unreflectively'.
27. Natural Reality / B. Modern Physics / 1. Relativity / a. Special relativity
Motion is not absolute, but consists in relation [Leibniz]
     Full Idea: In reality motion is not something absolute, but consists in relation.
     From: Gottfried Leibniz (On Motion [1677], A6.4.1968), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3
     A reaction: It is often thought that motion being relative was invented by Einstein, but Leibniz wholeheartedly embraced 'Galilean relativity', and refused to even consider any absolute concept of motion. Acceleration is a bit trickier than velocity.
