Man is an Animal, formidable both from his Passions and his Reason; his Passions often urging him to great Evils, and his Reason furnishing Means to achieve them. To train this Animal, and make him amenable to Order; to inure him to a Sense of Justice and Virtue, to withhold him from ill Courses by Fear, and encourage him in his Duty by Hopes; in short, to fashion and model him for Society, hath been the Aim of civil and religious Institutions; and, in all Times, the Endeavour of good and wise Men. The aptest Method for attaining this End, hath been always judged a proper Education.
George BerkeleyAnd what are these fluxions? The velocities of evanescent increments. And what are these same evanescent increments? They are neither finite quantities, nor quantities infinitely small, nor yet nothing. May we not call them the ghosts of departed quantities...?
George BerkeleyBut the velocities of the velocities - the second, third, fourth, and fifth velocities, etc. - exceed, if I mistake not, all human understanding.
