Copy Me

Philosopher John Locke published “An Essay Concerning Human Understanding” in 1689, in which he proposed the following criterion for personal identity: if you remember thinking something in the past, then you are the same person as he or she who did the thinking. Later philosophers raised various logical snarls, most of them caused by applying Boolean logic, the prevalent logic system at the time. It has been proposed that modern fuzzy logic can solve those problems, showing that Locke’s basic idea is sound if one treats personal identity as a continuous rather than discrete value.

防止愚善系統 3

Posted on by

一個「企圖做好人」的人，可能因為人格有嚴重的缺失，大大傷害了人也不知道。

例如，假設有異性向你示愛，但你卻對她，沒有愛情的感覺。明顯的恰當做法是，用最大方得體的語言，立刻斬釘截鐵地，拒絕她，除非她有自毀的傾向。

為什麼如果對方，沒有自毀傾向的話，你就應該立刻拒絕她呢？

如果你在愛情上，不喜歡她的話，你總有一天會拒絕她。如果你不立刻拒絕，到下次才說清楚的話，她只會加倍傷心。兩害取其輕，「現在傷心」總好過「未來加倍傷心」。

這一點我覺得很明顯，但是有些「企圖好人」，卻因為怕傷害對方，而拖泥帶水，在應該拒絕時不拒絕，到頭來令對方，加倍傷心。

防止自己愚善的第一個方法是，在應該「說不」時要立刻「說不」。

在意圖上，我們要盡力避免傷害人。同時，在知識上，我們要知道，在小部分情況下，無可避免會傷害到人。在迫不得已的情況下，在行動上，我們應該「眾害取其輕」，選擇一個對人，傷害最小的做法。

如果你在沒有可能的情況下，企圖令傷害降至零的話，你是愚善，因為結果你會，加重別人的傷心。

Batteries included

Posted on by

The Haskell Platform is a collection of software-packages, tools and libraries, which is to create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: “Batteries included”.

— Wikipedia on Haskell Platform

The quality of a programming language itself is only one component in the ability of application writers to get the job done. Programming languages can succeed or fail based on the breadth and quality of their library collection.
