The power to become habituated to his surroundings is a marked characteristic of mankind.

I'd rather be vaguely right than precisely wrong.

The treasury could fill old bottles with banknotes and bury them..and leave it to private enterprises on well-tried principles of laissez-faire to dig the notes up again.

Businessmen have a different set of delusions from politicians; and need, therefore, different handling. They are, however, much milder than politicians, at the same time allured and terrified by the glare of publicity....You could do anything you like with them, if you would treat them (even the big ones) not as wolves and tigers, but as domestic animals by nature, even though they have been badly brought up and not trained as you would wish.
