Kant bleg:
"Out of the crooked timber of humanity, no straight thing was ever made." Does anyone know the actual source for this in Kant, and the actual quote in German? A Google search for "krummen Holz" yields a number of different formulations and no actual citation. Does Isaiah Berlin (whose book I don't have on hand) give a citation?
UPDATE: Well, that was quick. Thanks, all!
"Aus so krummem Holze, als woraus der Mensch gemacht ist, kann nichts ganz Gerades gezimmert werden"
But I feel Berlin was too transliteral.
It's the original sin fallacy, nothing more.
I'm more interested in the contradiction between the spirit of that quote and Kant's admonishment against treating people "solely " as a means rather than an end in themselves.
(a) Humans are radically flawed, and hence all human endeavors will be radically flawed (something like the "krummes Holz" proposition).
(b) Humans should not be treated solely as means, but rather as ends in themselves.
Certainly, there is no logical contradiction between (a) and (b). Perhaps you mean that (a) together with one or more as yet unspecified propositions contradicts (b). If that's what you mean, what further propositions do you have in mind?
