Hector Macpherson, Herschel (1919)
“ And how can we argue and draw conclusions if the superior intellectual powers are not improved by frequent exercise in speculative researches? Half a dozen experiments made with judgment by a person who reasons well are worth a thousand random observations of insignificant matters of fact. But setting aside the very obvious consequences of improved faculties, the subjects of mere speculative knowledge are of the highest concern to those who love wisdom. ”
