Two great optical barriers, known technically as spherical and chromatic aberration the one due to a failure of the rays of light to fall all in one plane when focalized through a lens, the other due to the dispersive action of the lens in breaking the white light into prismatic colors confronted the makers of microscopic lenses, and seemed all but insuperable.
Just as in science the dispersive effect of specialism has led many thinkers to desire another order of minds specially devoted to generalism, to knitting together the results of the detailed investigations of others, so in conduct, morals and politics, it is more and more imperative to recall men's minds, and, in the first place, our own, to the large governing ideas by which after all our lesser rules and objects must stand or fall.
A refracting telescope which has been freed from the effects of chromatic aberration is called achromatic. The principle upon which its construction depends is that by combining lenses of different dispersive power the separation of the spectral colors in the image can be corrected while the convergence of the rays of light toward a focus is not destroyed.
His utilitarianism transcends our daily wants and seeks to provide for our eternal ones. He is, moreover, a mind whose workings turn in spiral form towards a central idea and therefore feels an instinctive antagonism to the dispersive habits of thought and sensation which such detailed observation of life usually entails.
