“The time makes no difference in the reason of the thing.”
Rex v. Inhabitants of Christchurch (1759), 2 Burr. Part IV. 949.

VIII. On Mind and Soul, and that the latter is immortal.
On the Gods and the Cosmos
Context: First, we must consider what soul is. It is, then, that by which the animate differs from the inanimate. The difference lies in motion, sensation, imagination, intelligence. Soul therefore, when irrational, is the life of sense and imagination; when rational, it is the life which controls sense and imagination and uses reason. The irrational soul depends on the affections of the body; it feels desire and anger irrationally. The rational soul both, with the help of reason, despises the body, and, fighting against the irrational soul, produces either virtue or vice, according as it is victorious or defeated.

“Happiness is not an ideal of reason but of imagination.”
Fundamental Principles of the Metaphysics of Ethics (1785)
