William D. Granger, How to Care for the Insane: A Manual for Nurses
“ Reason is that faculty by which we are able to make use of what we know and to acquire new knowledge. For instance, I know the distance between two places is sixty miles, and I know that the cars, going between the places, travel at the rate of twenty miles an hour, and that they leave at four o’clock. Without reason, I could never of myself, know the two new facts, that it would require three hours to make the journey, and that the arrival will be at seven o’clock. The faculty of reason is one of the most distinctive of the human mind. ”
