If we study nature aright, we shall find that its whole being is wisdom; life itself is wisdom. Look at the delicate structure of the eye, and the protection afforded it by the eyelid. Does not this prove that nature's wisdom is much more developed than the science and art of man? Has man ever been able to create what is not in nature? We know that the rain falls and waters the ground, and makes the plants grow, and we say that rain is the cause of all this, but if we delved deeper we should discover the cause of the rain. Even then the inner cause remains hidden.
