[简答题](46) Students of United States history, seeking to identify the circumstances that encouraged the emergence of feminist movements, have thoroughly investigated the mid-nineteenth-century American economic and social conditions that affected the status of women. These historinans, however, have analyzed less fully the development of specifically feminist ideas and activities during the same period. (47) Furthermore, the ideological origins of feminism in the United States have been obscured because, even when historians did take into account those feminist ideas and activities occurring within the United States, they failed to recognize that feminism was then a truly international movement actually centered in Europe.

[单项选择]Gottfried Wilhelm Leibniz
Leibniz was a German philosopher who belonged to the Rationalist school of philosophers, to which also belonged Descartes and Spinoza. But Leibniz was not only a philosopher, he was also a considerable authority on law, a diplomat, a historian and an outstanding mathematician — as is proved by his discovery in 1676, independently of Newton, of the Differential Calculus.
Leibniz was the son of a Professor of Philosophy of Leipzig University, who died when his son was only 6, but who left behind a fine collection of books which the young Leibniz read eagerly. Leibniz studied law at the University, and then, while in the service of the Elector of Mainz, he visited Paris and London and became acquainted with the learned men of his time. When he was 30 he became official librarian of the Brunswich family at Hanover, where he remained till he died.
His philosophy is set out in a short paper, The Mondadology, which he wrote two years before his death.
A. Gottfried Wilhelm Leibniz
B. George Berkeley
C. David Hume
