Many details are given about their customs of eating and drinking, about their mode of dressing, their employments, their wars. Campanella looks forward to a new mode of education, which is to be a study of nature, and not of Aristotle. He would not have his citizens waste their time in the consideration of what he calls ‘the dead signs of things.’ He remarks that he who knows one science only, does not really know that one any more than the rest, and insists strongly on the necessity of a variety of knowledge. More scholars are turned out in the City of the Sun in one year than by contemporary methods in ten or fifteen. He evidently believes, like Bacon, that henceforward natural science will play a great part in education, a hope which seems hardly to have been realized, either in our own or in any former age; at any rate the fulfilment of it has been long deferred.
