Secondly from the rational perspective the mathematical expectation (the amount of probability multiplied by the value of the probable ) of dealing with spiritual and otherworld thing and also the mathematical expectation of reflecting over and investigating these matters are infinite , while the mathematical expectation of the greatest worldly pleasure and joys is limited and as any sound reason would decree, once in doubt , we should choose the thing whose mathematical expectation is greater.

We can conclude, then that the second criterion also unproblematic and on its basis we can infer the rational necessity of thing.

4- Those who are obliged to defend their religion rationally. 5- Those who feel the necessity to search for a deeper understanding of divine knowledge. 6- Those scholars who are intellectually qualified to learn philosophy.
