Belief in God is rational. Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED.

moral objectivism
moral objectivism (like objectivism in general) seems to be entailed by the law of excluded middle and the correspondence theory of truth, along with a couple of what seem equally obvious observations about morality:
(1) There are moral propositions.
(2) So they are each either true or false. (by law of excluded middle) (3) And it's not that they're all false. Surely it is true, rather than false, that Josef Stalin's activities were bad. (Although some communists would disagree, we needn't take their view seriously, and moreover, even they would admit some moral judgement, such as, "Stalin was good.")
(4) So some moral judgements correspond to reality. (from 2,3, and the correspondence theory of truth)
(5) So moral values are part of reality. (which is objectivism)
But: Moral knowledge, if there is any, can't be empirical because, first, moral values are not perceptible; second, moral propositions are generally necessary, whereas empirical knowledge is generally contingent; and third, it doesn't seem possible to construct any kind of inductive arguments for moral conclusions.

Moral intuition is an exercise of reason. I note that I also believe in mathematical intuitions, metaphysical intuitions, psychological intuitions, and even physical intuitions -- and that all of these are exercises of reason in the same sense, and differ from one another and from ethical intuition simply in the subject matter to which intuition is applied. Since it will make some people feel better to reflect that moral intuition is not unusual but is just like several other uses of our intellect, I will list examples of these.
As mathematical intuitions, take "1+1=2" and "the shortest path between any two points is a straight line". As a metaphysical intuition, "The number of planets in the solar system is a contingent matter." As a psychological intuition, "Other things being equal, conscious beings will want to avoid pain." As physical intuitions, try "Forces cause motion" and "Physical causes are local; there is no action at a distance." Finally, as a moral intuition, consider "Torturing people just for the fun of it is wrong."
