There are great many reasons for studying what philosophers S1.______

have said in the past. One is that we cannot separate the

history of philosophy from which of science. Philosophy is S2.______

large discussion about matters on which few people are quite S3.______

certain, and those few hold opposite opinions. As knowledge

increases, philosophy buds off the sciences.

For an example, in the ancient world and the Middle Ages S4.______

philosophers discussed motion. Aristotle and St. Thomas Aquinas

taught that a moving body would slow down until a force was constantly S5.______

applied to it. They were wrong. It goes on moving unless

something slows it down. But they had good arguments on their

side, and if we study these, and the experiments which proved

them right, this will help us to distinguish truth from S6.______

false in the scientific controversies of today. We also see how S7.______

different philosopher reflects the social life of his day. Plato and S8.______

Aristotle, in the slave-owning society of ancient Greece, thought

man's highest state was contemplation rather than activity. In the

Middle Ages St. Thomas believed a regular feudal system of nine S9.______

ranks of angels. Herbert Spencer, in the time of free competition

between capitalists, found the key to progress in the survival of the S10.______

fittest. Thus Marxism is seen to fit into its place as the philosophy

for the workers, the only class with a future.
