Without natural gifts technical rules are useless.
A liar must have a good memory. -Mendacem oportet esse memorem
A great part of art consists in imitation. For the whole conduct of life is based on this: that what we admire in others we want to do ourselves.
Though ambition may be a fault in itself, it is often the mother of virtues.
There is no one who would not rather appear to know than to be taught.
It is fitting that a liar should be a man of good memory.
