Agnosticism, in fact, is not a creed, but a method, the essence of which lies in the rigorous application of a single principle. That principle is of great antiquity; it is as old as Socrates; as old as the writer who said, 'Try all things, hold fast by that which is good'; it is the foundation of the Reformation, which simply illustrated the axiom that every man should be able to give a reason for the faith that is in him, it is the great principle of Descartes; it is the fundamental axiom of modern science. Positively the principle may be expressed: In matters of the intellect, follow your reason as far as it will take you, without regard to any other consideration. And negatively: In matters of the intellect, do not pretend that conclusions are certain which are not demonstrated or demonstrable. That I take to be the agnostic position, which if a man keep whole and undefiled, he shall not be ashamed to look the universe in the face, whatever the future may have in store for him.The results of the working out of the agnostic principle will vary according to individual knowledge and capacity, and according to the general condition of science. That which is unproved today may be proved, by the help of new discoveries, tomorrow. The only negative fixed points will be those negations which flow from the demonstrable limitation of our faculties. And the only obligation accepted is to have the mind always open to conviction.That it is wrong for a man to say he is certain of the objective truth of a proposition unless he can provide evidence which logically justifies that certainty. This is what agnosticism asserts and in my opinion, is all that is essential to agnosticism.
For many years I have been asking myself why intelligent children act unintelligently at school. The simple answer is, "Because they're scared." I used to suspect that children's defeatism had something to do with their bad work in school, but I thought I could clear it away with hearty cries of "Onward! You can do it!" What I now see for the first time is the mechanism by which fear destroys intelligence, the way it affects a child's whole way of looking at, thinking about, and dealing with life. So we have two problems, not one: to stop children from being afraid, and then to break them of the bad thinking habits into which their fears have driven them.What is most surprising of all is how much fear there is in school. Why is so little said about it. Perhaps most people do not recognize fear in children when they see it. They can read the grossest signs of fear; they know what the trouble is when a child clings howling to his mother; but the subtler signs of fear escaping them. It is these signs, in children's faces, voices, and gestures, in their movements and ways of working, that tell me plainly that most children in school are scared most of the time, many of them very scared. Like good soldiers, they control their fears, live with them, and adjust themselves to them. But the trouble is, and here is a vital difference between school and war, that the adjustments children make to their fears are almost wholly bad, destructive of their intelligence and capacity. The scared fighter may be the best fighter, but the scared learner is always a poor learner.
