When my information changes, I alter my conclusions. What do you do, sir?

Investment based on genuine long-term expectations is so difficult today as to be scarcely practicable.

I conceive, therefore, that a somewhat comprehensive socialisation of investment will prove the means of securing an approximation to full employment.

Too large a proportion of recent "mathematical" economics are mere concoctions, as imprecise as the initial assumptions they rest on, which allow the author to lose sight of the complexities and interdependencies of the real world in a maze of pretentious and unhelpful symbols.

It is astonishing what foolish things one can temporarily believe if one thinks too long alone, particularly in economics.

When somebody persuades me I am wrong, I change my mind.

In the long run we are all dead.
