The man whose whole activity is diverted to inner meditation becomes insensible to all his surroundings. His passions are mere appearances, being sterile. They are dissipated in futile imaginings, producing nothing external to themselves.

Man seeks to learn, and man kills himself because of the loss of cohesion in his religious society; he does not kill himself because of his learning. It is certainly not the learning he acquires that disorganizes religion; but the desire for knowledge wakens because religion becomes disorganized.

A monomaniac is a sick person whose mentality is perfectly healthy in all respects but one; he has a single flaw, clearly localized. At times, for example, he has an unreasonable and absurd desire to drink or steal or use abusive language; but all his other acts and all his other thoughts are strictly correct.

In all history, we do not find a single religion without a Church.
