But what is progress going to do with the past, and with the present? How is it going to treat them? With ignominy, or respect? Should it break with them altogether, or rise out of them, with its roots still deep in the older time? What attitude shall progressives take toward the existing order, toward those institutions of conservatism, the Constitution, the laws, and the courts? Are those thoughtful men who fear that we are now about to disturb the ancient foundations of our institutions justified in their fear? If they are, we ought to go very slowly about the processes of change. If it is indeed true that we have grown tired of the institutions which we have so carefully and sedulously built up, then we ought to go very slowly and very carefully about the very dangerous task of altering them. We ought, therefore, to ask ourselves, first of all, whether thought in this country is tending to do anything by which we shall retrace our steps, or by which we shall change the whole direction of our development? I believe, for one, that you cannot tear up ancient rootages and safely plant the tree of liberty in soil which is not native to it. I believe that the ancient traditions of a people are its ballast; you cannot make a _tabula rasa_ upon which to write a political program. You cannot take a new sheet of paper and determine what your life shall be to-morrow. You must knit the new into the old. You cannot put a new patch on an old garment without ruining it; it must be not a patch, but something woven into the old fabric, of practically the same pattern, of the same texture and intention. If I did not believe that to be progressive was to preserve the essentials of our institutions, I for one could not be a progressive. * * * * * One of the chief benefits I used to derive from being president of a university was that I had the pleasure of entertaining thoughtful men from all over the world. I cannot tell you how much has dropped into my granary by their presence. I had been casting around in my mind for something by which to draw several parts of my political thought together when it was my good fortune to entertain a very interesting Scotsman who had been devoting himself to the philosophical thought of the seventeenth century. His talk was so engaging that it was delightful to hear him speak of anything, and presently there came out of the unexpected region of his thought the thing I had been waiting for. He called my attention to the fact that in every generation all sorts of speculation and thinking tend to fall under the formula of the dominant thought of the age. For example, after the Newtonian Theory of the universe had been developed, almost all thinking tended to express itself in the analogies of the Newtonian Theory, and since the Darwinian Theory has reigned amongst us, everybody is likely to express whatever he wishes to expound in terms of development and accommodation to environment.
