But it is of critical importance to ask ourselves what features which other animals do not possess have given human beings the very special capacitie… - Jacob Bronowski

And when we describe it as I shall do, it becomes plain that imagination is a specifically human gift. To imagine is the characteristic act, not of the poet's mind, or the painter's, or the scientist's, but of the mind of man.

We cannot hope to recapture today the terror that the mounted horse struck into the Middle East and Eastern Europe when it first appeared. That is because there is a difference of scale which I can only compare with the arrival of tanks in Poland in 1939, sweeping all before them. I believe that the importance of the horse in European history has always been underrated. In a sense, warfare was created by the horse, as a nomad activity. That is what the Huns brought, that is what the Phrygians brought, that is what finally the Mongols brought, and brought to a climax under Genghis Khan much later. In particular, the mobile hordes transformed the organisation of battle. They conceived a different strategy of war – a strategy that is like a war game; how, warmakers love to play games!

Life is not an examination; we do not get marks for the steps; what matters is getting the right answer. So it is perfectly possible to base a system of prediction on no principle except trying to get the right answer. This is exactly what all plants and animals do. The bat avoids obstacles by shouting at them that shrill cry just beyond my hearing, and then listens for the echo. Whatever system it has for translating the echo into a prediction it has found by evolution, and evolution has found it by trial and error.
