why do you think most philosophers were rich ?  because you can only think about the nebulous stuff AFTER all your immediate needs are met.  poor people think like animals because they face the same issues as animals face - such has starvation.  

a religious person is also like an animal because their "soul" is under constant threat ( of going to hell ) so like an animal or a peasant they are in survival mode.  they don't have the luxury of thinking.

but if you give up on your soul like an atheist, or on material things like Diogenes, then you are free to think.

as Mike Tyson said - everyone has a plan until they get punched in the face.  what this means is that you can't fight in survival mode and also think at the same time.

you have to give up all hope ( both for this life and the afterlife ) and become a total Gooner like me and then and only then can you be a great philosopher !
