Will

Arthur Schopenhauer famously said “Man can do what he wills but he cannot will what he wills”. In other words, although an agent may often be free to act according to a motive, the nature of that motive is determined.

Implications for morality

The Compatibilist might argue that determinism is not just compatible with any good definition of free will, but actually necessary. If one’s actions are not determined by one’s beliefs, desires, and character, then how could one possibly be held morally responsible for those actions?

Mind is related to the universal wave function.

至少兩個不同

這段改編自 2010 年 6 月 8 日的對話。

有三個方格,你要填上三個英文字母。

_ _ _

每一格都是由 {A, B, C, D, E, F, G, H, I, J} 十個字母中,抽其中一個出來。字母可以重複被抽中,例如,第一格是 A 的話,第二格都可能是 A。假設整個過程是隨機的,即是各個可能性的機會均等。那樣,「至少有兩個字母不同」的機會率是多少?

(HYC:好像有很多個可能,例如:AAB、ABB、BBA 和 EFG 等等。)

你可以試試這樣想:「至少兩個不同」即是「不是全部相同」。

P(at least two are different)

= P(not all the same)

= 1 – P(all the same)

你先計「全部相同」的機會率,然後用「一」去減它就可以。
