It may mean either (i) a mood or attitude to- ward life'in which men despair of attaining, or regard life as incapable of yielding, any real happiness or satisfaction; or (2) a philosoph- ical theory in which such a view of life is jus- tified by psychological and metaphysical rea- soning. Pessimism* as a comprehensive philosophical theory, is modern and even recent, bein^ con- nected with the names chiefly of Schopenhauer and Hartmann. For these thinkers the mis- ery of life is only nn outcome or expression of a profound irrationality in the very nature of the world principle itself. In Schopenhauer's philosophy, for example, the world principle is conceived as a blind will, whose restless striving can bring only dissatisfaction and mis- ery to the beings that arc its unite embodi- ments, so that the only hope for man lies in negating, as far as possible, this will in him- self. And this negation, he holds, is best achieved in that passionless or disinterested contemplation of beauty and truth which art and science open up to us, because in such contemplation we are freed for the time be- ins from the bondage of desire, and raised above the cravings and disappointments and miseries of our ordinary life into the rest and peace of an ideal world. Pestalozzi, Johann Heinrich (1746- 1827), Swiss educational theorist, was born in Zurich. About 1775 he gathered together a number of destitute children, and put into practice his educational theories, which were based largely on Rousseau's return to nature. After a five years' struggle, Pestalozzi with- drew from practical life, to think out the edu- cational problem. His Evening Hours of a Hermit was the first unit ot his meditations. Then came a social novel, Leonard and Ger- trude, which attracted much attention. Under the patronage of the Swiss government, he opened an experimental school at Berthoud. While there he published IIow Gertrude Edu- cates Her Children, which is the recognized exposition of the Pestalozzinn method. In 1805 Pestalozzi moved his school to Yverdcm, which here drew upon him the eyes of all Europe. Pestalozzi awoke men to a sense of responsibility to childhood. The many foreign teachers who came to him for training spread abroad his theories, which have become the commonplaces of the science of education. Pesth. Sec Budapest.
