"Let's not blame our body as it was the source of our great harms and evil and not even pour our angst on the things. Let's rather find the cause in our soul and, eradicated any useless wish and hope in the ephemeral things, let's achieve a total self-control. Because we are sad and depressed or by fear either by useless and limitless desires. If these passions are under control, we can achieve reason and happiness"
Porphyry, To Marcella 29
