"The scientific method, Thomas Henry Huxley once wrote, is nothing but the normal working of the human mind. That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes.Taking this point of view, we may conclude that science is not physics, biology, or chemistry--is not even a subject--but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning."
