in what he should and should not believe, and much besides. And what does our science reply?
It triumphantly announces how many millions of miles the sun is from the earth, with what rapidity light traverses space, how many millions of undulations of the ether a second are produced by light, and how many undulations of atmosphere by sound; it tells of the chemical composition of the Milky Way; it tells of a new element, helion, of micro-organisms and their excrements, of the points in the hand where electricity concentrates, of X-rays, and so on.
"But all this is not at all what I am in need of knowing," says the simple, sensible man. "I want to know how to live."
"I don't care what you are in need of knowing," replies science, "what you ask for refers to sociology. But before answering questions of sociology we must settle questions of zoology, botany, physiology—in short, biology. And in order to settle these questions it is first necessary to solve questions of physics, of chemistry; it is necessary also to agree as to the form of the infinitesimal atoms, and as to how it is that the ether with neither weight nor resistance transmits force."
And men, chiefly those who sit on the backs of others, and who can therefore conveniently wait, are satisfied by such answers, and continue sitting and yawning, awaiting what was promised. But the simple and sensible working-man, he on whose back the men studying science are sitting, the great mass of people, humanity at large, cannot be satisfied with such replies, and naturally ask in wonder, "But when will that be? We cannot wait. You yourselves say that you will find out all this after several generations. But we live, we are alive to-day and to-morrow we shall die, and therefore we must know how we are to live the life we are in now. Teach us, then."
"The stupid and ignorant man!" answers science; "he does not understand that what science serves is not utility but science. Science investigates that which is
