"That number is entirely the creature of the mind, even though the other qualities be allowed to exist without, will be evident to whoever considers, that the same thing bears a different denomination of number, as the mind views it with different respects."
— Berkeley, George (1685-1753)
(Part I, §12, p. 46)
