Book,  Paragraph

 1   I,  2 |        nature, we say, is their principle of movement. But all movement
 2   I,  2 |      mean those which possess a principle of movement in their own
 3   I,  5 |    totter. The reason is that a principle is great rather in power
 4   I,  9 |       its duration. On the same principle the fulfilment of the whole
 5  II,  2 |   body-and each may be called a principle. Above is the principle
