Now comes a delicate question, which is always being asked. If a perfect God created the universe, why is there imperfection in it? What we call the universe is what we see, and that is only this little plane of consciousness or reason, and beyond that we do not see at all. Now the very question is an impossible one. If I take up only a bit out of a mass and look at it, it seems to be imperfect. Naturally. The universe seems imperfect because we make it so. How? What is reason? What is knowledge? Knowledge is finding associations. You go into the street and see a man, and know it is a man. You have seen many men, and each one has made an impression on your mind, and when you now see this man, you calmly refer to your store of impressions, see many pictures of men there, and you put this new one with the rest, pigeon-hole it and are satisfied. When a new impression comes and it has associations in your mind, you are satisfied, and this state of association is called knowledge. Knowledge is, therefore, pigeon-holing one experience with the already existing fund of experience, and this is one of the great proofs that you cannot have any knowledge until you have already a fund in existence. If you are without experience, or if, as some European philosophers think, the mind is a _tabula rasa_, it cannot get any knowledge, because the very fact of knowledge is the recognition of the new by comparison with already existing impressions. There must be a store ready to which to refer a new impression. Suppose a child is born into this world without such a fund, it would be impossible for him to get any knowledge. Therefore the child must have been in a state in which he had a fund, and so knowledge is eternally going on. Show me any way of getting out of this. It is mathematical experience. This is very much like the Spencerian and other philosophies. They have seen so far that there cannot be any knowledge without a fund of past knowledge. They have drawn out the idea that the child is born with knowledge. They say that the cause has entered the effect. It comes in a subtle form in order to be developed. These philosophers say that these impressions with which the child comes, are not from the child’s own past, but were in his forefathers’; that it is hereditary transmission. Very soon they are going to find this theory untenable, and some of them are now giving hard blows to these ideas of heredity. Heredity is very good, but incomplete. It only explains the physical side. How do you explain the influence of environment? Many causes produce one effect. Environment is one of the modifying causes. On the other hand we in turn make our own environment, because as our past was, so we find our present. In other words, we are what we are here and now, because of what we have been in the past.
