Man could not live if he were entirely impervious to sadness. Many sorrows can be endured only by being embraced, and the pleasure taken in them naturally has a somewhat melancholy character.
Emile DurkheimThe 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.
Emile DurkheimA 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.
