Secondly, what does it mean today to be a mathematician? Hardly anyone recognizes you as a mathematician these days without a degree. And the effort taken to get a degree usually confines you to a job in your narrow field in academia. Where you have to publish or perish. C'est quoi la philosophie? No one has time for that. Thirdly, it's not just that mathematicians were philosophers, they were polymaths. There were entire fields of knowledge to master and in those days one man could still do it. Today you can expect a man to only master a narrow sub-field of mathematics, if that alone. Fourth, there were less distractions those days. Who has time to philosophize when there's porn and mongolian image boards to post on?
And fifth, even with all those factors you still get a once-in-a-blue moon mathematician-philosopher. Roger Penrose for example. You can bet any mathematician that's smart enough to be in schizo territory has dabbled in philosophy. But most of those have learned it's best to keep it to themselves.
