answers to the problems in [SICP]
<twb> Gumug: you don't want answers

Wizard Book: SICP

It may be contrary to the spirit of the SICP* to release answers to SICP; but since they're poor solutions, we'll do it anyway.

We'd like to converge upon SICP's unpublished answers through incremental community effort;§ and that's where you come in.

‡ Cf. Kant's Ding an sich; it's an article of faith, in other words, that answers to SICP exist. Or a necessary untruth; i.e., “die Unwahrheit als Lebensbedingung.” (Nietzsche, Jenseits von Gut und Böse, § 4.)

§ Incremental community effort is not unlike a Monte Carlo simulation: it converges upon the truth by a heroic sequence of untruth. The predicate here is consensus (cf. Wikipedia).
