"Gottlieb has got Hume's geniality down to a T. 'Every philosopher likes to think he has reached his conclusions via rigorous reasoning,' he says, with a collusive wink to his readers; in the 17th century, indeed, 'falling in love with geometry seems almost to have been an occupational hazard'. Take Descartes: he was notable for 'his faith in his own unusually bright light of reason', but 'perhaps he did not have all the answers'. As for Hobbes, he was so 'bedazzled' by a priori geometry that he 'got rather carried away' and ended up 'over-egging his pudding'. But Leibniz is the one you really have to watch, since, poor fellow, he 'did, in effect, tend to confuse his own mind with that of God'."
