I am part of the part that once was everything, Part of the darkness which gave birth to light… Mephistopheles, from Faust.

In all our academies we attempt far too much. ... In earlier times lectures were delivered upon chemistry and botany as branches of medicine, and the medical student learned enough of them. Now, however, chemistry and botany are become sciences of themselves, incapable of comprehension by a hasty survey, and each demanding the study of a whole life, yet we expect the medical student to understand them. He who is prudent, accordingly declines all distracting claims upon his time, and limits himself to a single branch and becomes expert in one thing.

No two men see the world exactly alike, and different temperaments will apply in different ways a principle that they both acknowledge.

We don't get to know anything but what we love.
