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 Durkheim

Sadness does not inhere in things; it does not reach us from the world and through mere contemplation of the world. It is a product of our own thought. We create it out of whole cloth. – Emile Durkheim
