Page "Cosmological argument" Paragraph 25

Thus, Leibniz ' argument is in esse, while Aquinas ' argument is both in fieri and in esse.

This distinction is an excellent example of the difference between a deistic view ( Leibniz ) and a theistic view ( Aquinas ).

As a general trend, the modern slants on the cosmological argument, including the Kalam argument, tend to lean very strongly towards an in fieri argument.
