The acts of the mind, wherein it exerts its power over simple ideas, are chiefly these three: 1. Combining several simple ideas into one compound one, and thus all complex ideas are made. 2. The second is bringing two ideas, whether simple or complex, together, and setting them by one another so as to take a view of them at once, without uniting them into one, by which it gets all its ideas of relations. 3. The third is separating them from all other ideas that accompany them in their real existence: this is called abstraction, and thus all its general ideas are made. -- John Locke, An Essay Concerning Human Understanding (1690)

It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years. -- John Von Neumann, circa 1949

We are the sum of our behaviours; excellence therefore is not an act but a habit. -- Aristotle.

The president was visiting NASA headquarters and stopped to talk to a man who was holding a mop. “And what do you do?” he asked. The man, a janitor, replied, “I’m helping to put a man on the moon, sir.” -- The little book of leadership
