The only sin is limitation. As soon as you once come up with a man's limitations, it is all over with him. Has he talents? has heenterprise? has he knowledge? It boots not. Infinitely alluring and attractive was he to you yesterday, a great hope, a sea to swim in; now, you have found his shores, found it a pond, and you care not if you never see it again.
A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber-room of his library, where he can get it if he wants it.
The value of an idea has nothing whatsoever to do with the sincerity of the man who expresses it.

The householder must always please his wife with money, clothes, love and faith and never do anything to disturb her. That man who has succeeded in getting the love of a chaste wife has succeeded in his religion and has all the virtues.
But whether the risks to which liberty exposes us are moral or physical our right to liberty involves the right to run them. A man who is not free to risk his neck as an aviator or his soul as a heretic is not free at all; and the right to liberty begins, not at the age of 21 years but 21 seconds.
Enlightenment is man's emergence from his self-imposed immaturity...No thing is required for this enlightenment.. .except freedom; and the freedom in question is the least harmful of all, namely, the freedom to use reason publicly in all matters.
I have very carefully studied Islam and the life of its Prophet (PBUH). I have done so both as a student of history and as a critic. And I have come to conclusion that Muhammad (PBUH) was indeed a great man and a deliverer and benefactor of mankind which was till then writhing under the most agonising Pain.
