William Van Natta

“to Hegel, history was like a running river. Every tiny movement in the water at a given spot in the river is determined by the falls and eddies in the water higher upstream. But these movements are determined, too, by the rocks and bends in the river at the point where you are observing it.

the history of thought--or of reason--is like this river. The thoughts that are washed along with the current of past tradition, as well as the material conditions prevailing at the time, help to determine how you think. You can therefore never claim that any particular thought is correct for ever and ever. But the thought can be correct from where you stand”
