A new interest in the God of the orthodox Hebrew-Christian tradition has arisen recently among contemporary philosophers. This new interest in theism can be traced to the demise of logical positivism, a lack of intellectual rigor in theological liberalism, and the increased sophistication of theistic arguments. Two arguments illustrate the many contemporary proofs for theism that have attracted wide interest. One argues that belief in God is rational apart from any special evidence. The other, called the kalam cosmological argument, maintains that everything which begins has a cause, the universe had a beginning, and therefore, the universe has a cause. This argument is supported by the reasonableness of a series of choices, beginning with whether or not the universe had a beginning. These arguments are satisfying proof of the existence of God for those who are philosophically inclined.
