Does the Torah require me to believe/know that God exists based on premises that I consider to be and reason to be certainties? Is it proper or even just ok to believe that God exists based on uncertainties?
To clarify- the position of uncertainty I'm entertaining is to say that although I am not certain that God exists and is One and interacts with the world etc. (in the way that I'm certain of other things), nevertheless I'm willing to decide to accept the proposition for many different not totally convincing reasons.
To clarify a bit further- I will not be left with doubt. I'm not unsure if God exists. I believe that God exists, but my belief is based on a decision to accept the proposition that God exists based on an uncertain chain of reasoning.
(I know that it seems like I'm double talking, but I don't think that I contradicted myself.)
Is this position explicitly discussed?
(The impetus for my asking this is a youtube video of Moshe Halbertal discussing Faith in which he seems to advance such a concept based on R Chasdai Crescas and William James. It's at approximately the 20 minute mark.)
