We are all, very properly, familiar with the idea that in every age the human mind is deeply influenced by the accepted Model of the universe. But there is a two-way traffic; the Model is also influenced by the prevailing temper of mind. We must recognise that what has been called 'a taste in universes' is not only pardonable but inevitable. We can no longer simply dismiss the change of Models as a simple progress from error to truth. No Model is a catalogue of ultimate realities, and none is a mere fantasy. Each is a serious attempt to get in all the phenomena known at a given period, and each succeeds in getting in a great many. But also, no less surely, each reflects the prevalent psychology of an age as much as it reflects the state of that age's knowledge. Hardly any battery of new facts could have persuaded a Greek that the universe had an attribute so repugnant to him as infinity; hardly any such battery could persuade a modern that it is hierarchical.
