"Who knows, the mind has the key to all things besides" — Amos Bronson Alcott

Intelligence is the wife, imagination is the mistress, memory is the servant

Man is the most intelligent of the animals - and the most silly

Man becomes man only by his intelligence, but he is man only by his heart

It is the mark of a truly intelligent person to be moved by statistics

Character is higher than intellect. A great soul will be strong to live as well as think

An intellectual is someone whose mind watches itself
