Avicenna or Descartes?

erm
who is avicenna ?

Descartes. For a couple of reasons.

I have no idea who the first person is.
Descartes arguments around theology are pretty good.
His 'I think therefore I am' lead me to the joke:

Descartes walks into a bar and orders a drink. After a while the bartender asks, 'would you like another?' then Descartes replies 'I think not!' and disappears.

It gets me all the bitches.

That's Avicenna, and I was thinking Des Cartes because of his mathematical recognition in modern life but Avicenna because of what he actually theorised about is interesting.

Yes exactly, so would you go with Descartes? Thanks for the help!

Avicenna. He also inspired other Egyptian and Ayyubid Polymaths to follow his ideologies etc his theorems on philosophy aren't all that insightful in due part to his religion and the heretical view of Greek and Roman predecessors.

Descartes is just boring, and his argument is more theological than philosophical.

So wait, are many of Avicenna's theories successful in modern life? That is part of the question, and I need to assess theories that are and aren't.

I would say neither of these figures play any real significance in modern theories, no.

Avicenna to a degree, was the hegemony tutor of later Islamic scholars which protected and revitalized the work of the Greeks, which in turn, has led to the renaissance of philosophy in Germany during the Renaissance ergo to modern day, but he as a figure, contributed little to nothing.
