...For natural science he [Otto von Bismarck] shewed little interest, and indeed at that time it scarcely could be reckoned among the ordinary subjects of education; philosophy he pursued rather as a man than as a student, and we are not surprised to find that it was Spinoza rather than Kant or Fichte or Hegel to whom he devoted most attention, for he cared more for principles of belief and the conduct of life than the analysis of the intellect.
...He [Otto von Bismarck] astonished his friends by the amount and variety of his reading; it was at this time that he studied Spinoza. It is said that he had among his friends the reputation of being a liberal; it is probable enough that he said and did many things which they did not understand; and anything they did not understand would be attributed to liberalism by the country gentlemen of Pomerania; partly no doubt it was due to the fact that in 1843 he came back from Paris wearing a beard.
