Robert A. Heinlein Mind Quotations

Jealousy is a disease, love is a healthy condition. The immature mind often mistakes one for the other, or assumes that the greater the love, the greater the jealousy -- in fact, they're almost incompatible; one emotion hardly leaves room for the other. Both at once can produce unbearable turmoil...

It is a truism that almost any sect, cult, or religion will legislate its creeds into law if it acquires the political power to do so, and will follow it by suppressing opposition, subverting all education to seize early the minds of the young, and by killing, locking up, or driving underground all heretics.

The mind's ability to rationalize it's own shortcomings is unlimited; I am no exception.

God is omnipotent, omniscient, and omnibenevolent - it says so right here on the label. If you have a mind capable of believing all three of these attributes simultaneously, I have a wonderful bargain for you. No checks, please. Cash and in small bills.

Why do some people act as if making money offended their delicate minds? I am out for a legitimate profit, and not ashamed of it; the fact that people will pay money for my goods and services shows that my work is useful.

Anything which is physically possible can always be made financially possible; money is a bugaboo of small minds.

His was not a small mind bothered by logic and consistency.
