Philosophy Cleaning the Lens
“... the philosopher, who perfectly possesses the science of the general, needs the science of all things, for a man of such circumstances knows in a certain way everything that is understood under the general. But it can also be said that it is very difficult for man to come to the more general knowledge; such as that the things that are subject to them are far beyond the reach of the senses.” (Aristotle, Metaphysics, Book First )
