We have no knowledge, that is, no general principles drawn from the contemplation of particular facts, but what has been built up by pleasure, and exists in us by pleasure alone. The Man of Science, the Chemist and Mathematician, whatever difficulties and disgusts they may have had to struggle with, know and feel this. However painful may be the objects with which the Anatomist's knowledge is connected, he feels that his knowledge is pleasure; and where he has no pleasure he has no knowledge.
One solace yet remains for us who came Into this world in days when story lacked Severe research, that in our hearts we know How, for exciting youth's heroic flame, Assent is power, belief the soul of fact.
On Man, on Nature, and on Human Life, Musing in solitude, I oft perceive Fair trains of images before me rise, Accompanied by feelings of delight Pure, or with no unpleasing sadness mixed.
When from our better selves we have too long been parted by the hurrying world, and droop. Sick of its business, of its pleasures tired, how gracious, how benign is solitude.
