"Human beings are by nature more partial to belief than to knowledge. Why? Because belief is spontaneous and instinctive, the product of thoughts, feelings and personal desires, whereas knowledge requires study, reflection and experience. Belief, therefore, always precedes knowledge. As soon as you know something, you leave the realm of belief, but your belief is then transferred to another object a little further off… until knowledge comes once again to take its place. Knowledge is like the horizon: the more you move towards it, the more it retreats into the distance, and as a result you never stop advancing. In order to progress, then, you must replace your beliefs with certainties based on true knowledge."
