terial forces or economies, the increase of knowledge, the betterment of government, etc., have the same effect as improvements in the arts, it will not be necessary in this view to consider them separately. What bearing intellectual or moral progress, merely as such, has upon our problem we may hereafter consider. We are at present dealing with material progress, to which these things contribute only as they increase wealth-producing power, and shall see their effects when we see the effect of improvements in the arts.
To ascertain the effects of material progress upon the distribution of wealth, let us, therefore, consider the effects of increase of population apart from improvement in the arts, and then the effect of improvement in the arts apart from increase of population.
