Successful manipulation may be mistaken for intelligence.

GMG

Lying is a base vice....  Our intelligence being by no other way communicable to one another but by a particular word, he who falsifies that betrays public society....  it breaks all our correspondence, and dissolves all the ties of government. 

Montaigne

Let us boldly appeal to those who are in public affairs; let them lay their hands upon their hearts, and then say whether, on the contrary, they do not rather aspire to titles and offices and that tumult of the world to make their private advantage at the public expense. The corrupt ways by which in this our time they arrive at the height to which their ambitions aspire, manifestly enough declares that their ends cannot be very good. 

Michel de Montaigne
