Writing of abstract thought, he says : " I err, therefore I am," and continues in subsequent words to amplify

The editor of the volume referred to mentions that the Hindoo thinker has approached the subject in another manner. The Hindoo seer, writing long before Augustine, says, I am, therefore I think," whic t one may possibly con- sider is characteristic of the Indian method of approach to the same subject.—I am, Sir, &c.,
