Chapter XIII.--Ecphantus; His Scepticism; Tenet of Infinity.
One Ecphantus, a native of Syracuse, affirmed that it is not possible to attain a true knowledge of things. He defines, however, as he thinks, primary bodies to be indivisible, [103] and that there are three variations of these, viz., bulk, figure, capacity, from which are generated the objects of sense. But that there is a determinable multitude of these, and that this is infinite. [104] And that bodies are moved neither by weight nor by impact, but by divine power, which he calls mind and soul; and that of this the world is a representation; wherefore also it has been made in the form of a sphere by divine power. [105] And that the earth in the middle of the cosmical system is moved round its own centre towards the east. [106]
