But what is the problem? Common English, I might perhaps say common civilised thought, ignores it. Our habitual instructors, our ordinary conversation, our inevitable and ineradicable prejudices tend to make us think that 'Progress' is the normal fact in human society, the fact which we should expect to see, the fact which we should be surprised if we did not see. But history refutes this. The ancients had no conception of progress; they did not so much as reject the idea; they did not even entertain the idea. Oriental nations are just the same now. Since history began they have always been what they are. Savages, again, do not improve; they hardly seem to have the basis on which to build, much less the material to put up anything worth having. Only a few nations, and those of European origin, advance; and yet these think--seem irresistibly compelled to think--such advance to be inevitable, natural, and eternal. Why then is this great contrast? Before we can answer, we must investigate more accurately. No doubt history shows that most nations are stationary now; but it affords reason to think that all nations once advanced. Their progress was arrested at various points; but nowhere, probably not even in the hill tribes of India, not even in the Andaman Islanders, not even in the savages of Terra del Fuego, do we find men who have not got some way. They have made their little progress in a hundred different ways; they have framed with infinite assiduity a hundred curious habits; they have, so to say, screwed themselves into the uncomfortable corners of a complex life, which is odd and dreary, but yet is possible. And the corners are never the same in any two parts of the world. Our record begins with a thousand unchanging edifices, but it shows traces of previous building. In historic times there has been little progress; in prehistoric times there must have been much. In solving, or trying to solve, the question, we must take notice of this remarkable difference, and explain it, too, or else we may be sure our principles are utterly incomplete, and perhaps altogether unsound. But what then is that solution, or what are the principles which tend towards it? Three laws, or approximate laws, may, I think, be laid down, with only one of which I can deal in this paper, but all three of which it will be best to state, that it may be seen what I am aiming at.
