The study of philosophies should make our own ideas flexible. We are all of us apt to make certain general ideas for granted, and call them common sense. We should learn that other people have held quite different ideas, but that our own have started as very original guesses of philosophers.
A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a great many of the questions in which philosophers still argue. For example, Plato thought that when we saw something, one ray of light came to it from the sun, and the other from our eyes and that seeing was something like feeling with a stick. We now know that the light comes from the sun,and is reflected into our eyes. We don’t know in much detail how the changes in our eyes give to sensation. But there is every, reason to think that as we learn more about the physiology of the brain,we shall do so, and that the great philosophical problems about knowledge are going to be pretty full cleared up.
But if our descendants know the answers to these questions and others that perplex us today, there would still be one field of which they do not know, namely the future. While exact our science, we cannot know it as we know the past. Philosophy may be described as argument about things of which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment. That is one reason that Marx and Engels quite rightly wrote to many philosophical problems that interested in their contemporaries. ______
