"We might almost accuse nature of falsehood. One sees himself behind a mirror when nothing is there. A straight pole leaning in a pool is bent to appearance. The sun seems to rise and set, but moves not at all. We see it before it rises and after it sets. These and numberless other cases might be adduced to prove the deceitfulness of nature. Nay, they prove rather that education policy is the law of our being, and that here, as elsewhere, he who would not be self-deceived, must study nature's laws, must become educated."
