A pun is not bound by the laws which limit nicer wit. It is a pistol let off at the ear; not a feather to tickle the intellect. (Quote by - Charles Lamb)

Intuition is a spiritual faculty and does not explain, but simply points the way. (Quote by - Florence Scovel Shinn)

Instinct perfected is a faculty of using and even constructing organized instruments; intelligence perfected is the faculty of making and using unorganized instruments. (Quote by - Henri Louis Bergson)
