" ¿HE who knows me only by my writings does not know me,¿ said Leibniz. These words¿true, indeed, of every writer, but true of Leibniz in a way which gives a peculiar interest and charm to his life¿must be our excuse for prefacing what is to be said of his ¿New Essays concerning the Human Understanding¿ with a brief biographical sketch.Gottfried Wilhelm Leibniz was born in Leipzig June 21, 1646. His father, who died when Leibniz was only six years old, was a professor in the university and a notary of considerable practice. From him the future philosopher seems to have derived his extraordinary industry and love of detail. Such accounts as we have of him show no traces of the wonderful intellectual genius of his son, but only a diligent, plodding, faithful, and religious man, a thoroughly conscientious husband, jurist, and professor. Nor in the lines of physical heredity can we account for the unique career of Leibniz by his mother¿s endowments. The fact, however, that she was patient in all trial, living in peace with her neighbors, anxious for unity and concord with all people, even with those not well disposed to her, throws great light upon the fundamental trait of Leibniz¿s ethical nature"
