"What we have forgotten is that thoughts and words are conventions and that it is fatal to take conventions too seriously. A convention is a social convenience, as, for example, money ... but it is absurd to take money too seriously, to confuse it with a real wealth ... In somewhat the same way, thoughts, ideas, and words are "coins" for real things." —Alan Wilson Watts, The Wisdom of Insecurity: A Message for an Age of Anxiety
"Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve." —Karl Popper
"In theory, there is no difference between theory and practice. But in practice, there is." —Benjamin Brewster
