it is possible for the same thing both to be and not to be. - David Hume

When men are most sure and arrogant they are commonly most mistaken, giving views to passion without that proper deliberation which alone can secure them from the grossest absurdities.

Beauty in things exists in the mind which contemplates them

What is the soul of man? A composition of various faculties, passions, sentiments, ideas; united, indeed, into one self or person, but still distinct from each other. When it reasons, the ideas which are the parts of its discourse arrange themselves in a certain form or order, which is not preserved entire for a moment, but immediately gives place to another arrangement. New opinions, new passions, new affections, new feelings arise which continually diversify the mental scene and produce in it the greatest variety and most rapid succession imaginable.
