However, let us consider things for a moment from the standpoint of those whose ideal is material 'welfare', and who therefore rejoice at all the improvements to life furnished by modern 'progress'; are they quite sure they are not being duped? Is it true that, because they dispose of swifter means of communication and other things of the kind, and because of their more agitated and complicated manner of life, men are happier today than they were formerly? The very opposite seems to us to be true: disequilibrium cannot be a condition of real happiness. Moreover, the more needs a man has, the greater the likelihood that he will lack something, and thereby be unhappy; modern civilization aims at creating more and more artificial needs, and as we have already said, it will always create more needs than it can satisfy, for once one has started on this path, it is very hard to stop, and, indeed, there is no reason for stopping at any particular point. It was no hardship for men to do without things that did not exist and of which they had never dreamed; now, on the contrary, they are bound to suffer if they lack these things, since they have become accustomed to consider them as necessities, with the result that they have, in fact, really become necessary to them. Therefore men struggle in every possible way to obtain the means of procuring material satisfactions, the only ones that they are capable of appreciating: they are interested only in 'making money', because it is money that enables them to obtain these things, the more of which they have, the more they wish to have, as they go on discovering fresh needs; and this passion becomes for them the sole end in life. Hence the savage competition certain evolutionists have raised to the dignity of a scientific law under the name of 'the struggle for existence', whose logical consequence is that only the strongest, in the narrowly material sense of the word, have a right to exist.
