A book on the atomic theory, classic also; four elaborate mathematical and experimental volumes on what he called psychophysics--many persons consider Fechner to have practically founded scientific psychology in the first of these books; a volume on organic evolution, and two works on experimental aesthetics, in which again Fechner is considered by some judges to have laid the foundations of a new science, must be included among these other performances. Of the more religious and philosophical works, I shall immediately give a further account. All Leipzig mourned him when he died, for he was the pattern of the ideal german scholar, as daringly original in his thought as he was homely in his life, a modest, genial, laborious slave to truth and learning, and withal the owner of an admirable literary style of the vernacular sort. The materialistic generation, that in the fifties and sixties called his speculations fantastic, had been replaced by one with greater liberty of imagination, and a Preyer, a Wundt, a Paulsen, and a Lasswitz could now speak of Fechner as their master. His mind was indeed one of those multitudinously organized cross-roads of truth which are occupied only at rare intervals by children of men, and from which nothing is either too far or too near to be seen in due perspective. Patientest observation, exactest mathematics, shrewdest discrimination, humanest feeling, flourished in him on the largest scale, with no apparent detriment to one another. He was in fact a philosopher in the 'great' sense, altho he cared so much less than most philosophers care for abstractions of the 'thin' order. For him the abstract lived in the concrete, and the hidden motive of all he did was to bring what he called the daylight view of the world into ever greater evidence, that daylight view being this, that the whole universe in its different spans and wave-lengths, exclusions and envelopments, is everywhere alive and conscious. It has taken fifty years for his chief book, 'Zend-avesta,' to pass into a second edition (1901). 'One swallow,' he cheerfully writes, 'does not make a summer. But the first swallow would not come unless the summer were coming; and for me that summer means my daylight view some time prevailing.'
