The human condition can almost be summed up in the observation that, whereas all experiences are of the past, all decisions are about the future. It is the great task of human knowledge to bridge this gap and to find those patterns in the past which can be projected into the future as realistic images.

As far as many statistical series that are related to activities of mankind are concerned, the date that divides human history into two equal parts is well within living memory. The world of today is as different from the world I was born in as that world was from Julius Caesar s. I was born in the middle of human history, to date, roughly. Almost as much has happened since I was born as happened before.

We should always bear in mind that numbers represent a simplification of reality.

Production functions involving only land, labor and capital... never work and never explain economic development.

Anyone who believes exponential growth can go on forever in a finite world is either a madman or an economist.

In any evolutionary process, even in the arts, the search for novelty becomes corrupting.

Where there is hypocrisy, there is hope.
