“We must always take care that we do not become so devoted to one branch of learning that we neglect the others, nor should we, by applying ourselves too closely to natural science neglect the study of morals or the business of everyday life.”
Semper autem cavendum est, nec, si uni iungamur arti, ut reliquas negligamus, neve naturalibus inhaerentes studiis ac contemplationibus, quae moralia sunt postponamus et rebus abducamur agendis.
-Aeneas Silvius Piccolomini, de Liberorum Educatione, chp. 94
This sentiment is echoed in David Hume’s Enquiry Concerning Human Understanding, section 1:
“Be a philosopher; but, amidst all your philosophy, be still a man.”
