Law of Thought - Avicenna and Persian Logic

Avicenna and Persian Logic

The Persian philosopher, Ibn Sina (Avicenna), once wrote the following response to opponents of the law of noncontradiction:

"Anyone who denies the law of non-contradiction should be beaten and burned until he admits that to be beaten is not the same as not to be beaten, and to be burned is not the same as not to be burned." (Avicenna, Metaphysics)

Famous quotes containing the words persian and/or logic:

    Oh! thou clear spirit of clear fire, whom on these seas I as Persian once did worship, till in the sacramental act so burned by thee, that to this hour I bear the scar; I now know thee, thou clear spirit, and I now know that thy right worship is defiance. To neither love nor reverence wilt thou be kind; and e’en for hate thou canst but kill; and all are killed. No fearless fool now fronts thee.
    Herman Melville (1819–1891)

    The usefulness of madmen is famous: they demonstrate society’s logic flagrantly carried out down to its last scrimshaw scrap.
    Cynthia Ozick (b. 1928)
