Faith is like love, it cannot be forced. Therefore it is a dangerous operation if an attempt be made to introduce or bind it by state regulations; for, as the attempt to force love begets hatred, so also to compel religious belief produces rank unbelief.

In youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating qualityof the mind. Hence, youth is the time for poetry, and age is more inclined to philosophy. In practical affairs it is the same: a man shapes his resolutions in youth more by the impression that the outward world makes upon him; whereas, when he is old, it is thought that determines his actions.

The work of genius may be music, philosophy, painting, or poetry; it is nothing for use or profit. To be useless and unprofitable is one of the characteristics of genius; it is their patent of nobility.
