This is a train of thought that I see a lot that isn't right. Philosophical civs actually get less benefit from pacificism or the parthenon than non-philosophical civs do. Therefore I'd be more likely to run pacifism as a non-philosophical civ than as a philosophical one.

But if you're running philosophical, you should probably be aggressively pursuing GPs (or you're wasting a trait). Since there's more emphasis on GPs, that extra 100% will most likely be worth more.
Both of you are too vehement, and the truth is that the benefit of Pacifism is most typically about the same for the two cases.
The important fact is that, because each GP costs more than the last one, the number of GP that you generate grows only as the square root of the number of GPP that you generate. So, the Philosophical civ with Pacifism generates 22% more GP than without: the increase from +100% GPP to +200% GPP is a factor of 1.5, and sqrt(1.5) = 1.22. While, the non-Philosophical civ with Pacifism generates 41% more GP than without: the increase from +0% GPP to +100% GPP is a factor of 2.0, and sqrt(2.0) = 1.41.
If the Philosophical civ generates X times as many GPP as the non-Philosophical civ,
before any bonuses, then it's generating sqrt(2.0*X) times as many GP as the non-Philosophical civ, including its Philosophical bonus. Thus the Philosophical civ adds 0.22/0.41 * sqrt(2.0*X) times as many "extra" GP as the non-Philosophical civ, with Pacifism, or sqrt(0.58*X).
Thus, the point where the two get an equal benefit is when the Philosophical civ is investing about twice as heavily in generating GPP as the non-Philosophical civ. And I think this is pretty close to the "usual" ratio, so, usually the benefits for the two civs are roughly the same.
