And happily the signs of this more moral public opinion are already showing themselves. It is becoming a tacitly-received doctrine that the rich should not, as in by-gone times, spend their lives in personal gratification; but should devote them to the general welfare. Year by year is the improvement of the people occupying a larger share of the attention of the upper classes. Year by year are they voluntarily devoting more and more energy to furthering the material and mental progress of the masses. And those among them who do not join in the discharge of these high functions, are beginning to be looked upon with more or less contempt by their own order. This latest and most hopeful fact in human history--this new and better chivalry--promises to evolve a higher standard of honour; and so to ameliorate many evils: among others those which we have detailed. When wealth obtained by illegitimate means inevitably brings nothing but disgrace--when to wealth rightly acquired is accorded only its due share of homage, while the greatest homage is given to those who consecrate their energies and their means to the noblest ends; then may we be sure that along with other accompanying benefits, the morals of trade will be greatly purified. FOOTNOTES: [Footnote 47: From "Essays: Moral, Political and Aesthetic," 1864.] ON THE PHYSICAL BASIS OF LIFE[48] THOMAS HENRY HUXLEY In order to make the title of this discourse generally intelligible, I have translated the term "Protoplasm," which is the scientific name of the substance of which I am about to speak, by the words "the physical basis of life." I suppose that, to many, the idea that there is such a thing as a physical basis, or matter, of life may be novel--so widely spread is the conception of life as a something which works through matter, but is independent of it; and even those who are aware that matter and life are inseparably connected, may not be prepared for the conclusion plainly suggested by the phrase, "_the_ physical basis or matter of life," that there is some one kind of matter which is common to all living beings, and that their endless diversities are bound together by a physical, as well as an ideal, unity. In fact, when first apprehended, such a doctrine as this appears almost shocking to common sense. What, truly, can seem to be more obviously different from one another, in faculty, in form, and in substance, than the various kinds of living beings? What community of faculty can there be between the brightly-coloured lichen, which so nearly resembles a mere mineral incrustation of the bare rock on which it grows, and the painter, to whom it is instinct with beauty, or the botanist, whom it feeds with knowledge?
