“Indulge your passion for science, says Nature, but let your science be
human, and such as may have a direct reference to action and society.
Abstruse thought and profound researches I prohibit, and will severely
punish, by the pensive melancholy which they introduce, by the endless
uncertainty in which they involve you, and by the cold reception which
your pretended discoveries shall meet with, when communicated.
Be a philosopher; but, amidst all your philosophy, be still a man”
(David Hume, An enquiry concerning Human Understanding)
