I concede that if causality is not assumed, the cosmological argument dissolves. So I will just assume the existence of causality. This seems reasonable given that the same assumption is made in science, I think. Tallis' views cannot cohere with the methodology of many sciences, since these sciences often presuppose it: eg. these icebergs are melting because of XYZ reasons.
Also, it seems that the word "God" has a lot of baggage along with it. Some posters have referred to "sky-father" or some type of objectified thing -- and understandably so, given the religious claims that exist in the world -- whereas the God to which the cosmological argument points is beyond objectification/space/time. So I will use the term "X" to refer to this thing.
And after some thought, it seems to me that the cosmological argument does indicate
something (say, X), about which the use of the term
God is, incidentally, reasonable. For, if one holds the view that space and time began with the big bang (mainstream cosmological view, I think), then that which was responsible for the big bang must have transcended time and space. Admittedly, X is thereby inferred to be merely supra-spatiotemporal, and not all-good or all-loving. X is something quite amazing, though, since X was responsible for all the matter and energy in the universe.
But I can think of two arguments showing that if X is beyond time and space, X must be good.
1. If X is beyond time, then X cannot change.
2. Evil implies change.
3. Goodness is essentially static, and tied up with the nature of being.
4. Therefore, X is good.
1. Love is of the nature of unity.
2. If X is the cause of the universe, then X is something unified.
3. Therefore, one of the predicates of X is "love-nature."
Therefore, adopting mainstream scientific views on reality (namely, assuming the existence of causality, current cogency of big-bang theory), it seems that the cosmological argument points to cause-of-the-universe X, where X = (i) beyond time and space, (ii) something so amazing that all the matter and energy came from it.
