In the Desert of Science.—As the man of science proceeds on his modest and toilsome wanderings, which must often enough be journeys in the desert, he is confronted with those brilliant mirages known as “philosophic systems.” With magic powers of deception they show him that the solution of all riddles and the most refreshing draught of true water of life are close at hand. His weary heart rejoices, and he well-nigh touches with [pg 027] his lips the goal of all scientific endurance and hardship, so that almost unconsciously he presses forward. Other natures stand still, as if spellbound by the beautiful illusion: the desert swallows them up, they become lost to science. Other natures, again, that have often experienced these subjective consolations, become very disheartened and curse the salty taste which these mirages leave behind in the mouth and from which springs a raging thirst—without one's having come one step nearer to any sort of a spring.
