I know what 'logically valid' means, and the Cosmological argument is a Valid construct. The concussion can't be false if the premises are true. Whether it is sound or not is another matter and the obvious premise to attack is the first one regarding the impossibility of the infinite regress and that there must be a first uncaused cause.uwot wrote:You misunderstand logic. The job of logic is to determine whether arguments are valid. Whether they are sound, 'true' if you will, depends on the state of the universe. There is no reason to assume that the universe is ultimately logical. For instance, the premise 'The universe popped into existence completely spontaneously' is only 'illogical' if you accept the premise "There must be a first uncaused cause."
Can you do better than 'that's bullshit'? Can you prove that there can be an infinite regress of causation?
