The chief benefit, which results from philosophy, arises in an indirect manner, and proceeds more from its secret, insensible influence, than from its immediate application.David Hume
The abilities of man must fall short on one side or the other, like too scanty a blanket when you are abed. If you pull it upon your shoulders, your feet are left bare; if you thrust it down to your feet, your shoulders are uncovered.Thomas Paine
There are two distinct classes of what are called thoughts: those that we produce in ourselves by reflection and the act of thinking and those that bolt into the mind of their own accord.Thomas Paine
