Immanuel Kant quotes - page 3
Newton... (after having remarked that geometry only requires two of the mechanical actions which it postulates, namely, to describe a straight line and a circle) says: geometry is proud of being able to achieve so much while taking so little from extraneous sources. One might say of metaphysics, on the other hand: it stands astonished, that with so much offered it by pure mathematics it can effect so little. In the meantime, this little is something which mathematics indispensably requires in its application to natural science, which, inasmuch as it must here necessarily borrow from metaphysics, need not be ashamed to allow itself to be seen in company with the latter.
Immanuel Kant
Collectively, the more civilized men are, the more they are actors. They assume the appearance of attachment, of esteem for others, of modesty, and of disinterestedness, without ever deceiving anyone, because everyone understands that nothing sincere is meant. Persons are familiar with this, and it is even a good thing that this is so in this world, for when men play these roles, virtues are gradually established, whose appearance had up until now only been affected. These virtues ultimately will become part of the actor's disposition. To deceive the deceiver in ourselves, or the tendency to deceive, is a fresh return to obedience[.].
