The man of system is apt to be very wise in his own conceit. In the great chess board of human society, every single piece has a principle of motion of its own altogether different from that which the legislature might choose to impress upon it
Adam SmithThe machines that are first invented to perform any particular movement are always the most complex, and succeeding artists generally discover that, with fewer wheels, with fewer principles of motion, than had originally been employed, the same effects may be more easily produced. The first systems, in the same manner, are always the most complex.
Adam SmithPoor David Hume is dying fast, but with more real cheerfulness and good humor and with more real resignation to the necessary course of things, than any whining Christian ever dyed with pretended resignation to the will of God.
