 In the dynamical antinomies, Kant changes his strategy somewhat. Rather than arguing (as in the mathematical antinomies) that both conclusions are false, Kant suggests that both sides to the dispute might turn out to be correct. This option is available here, and not in the two mathematical antinomies, because the proponents of the thesis arguments are not committing themselves solely to claims about spatio-temporal objects. In the third antinomy, the thesis contends that in addition to mechanistic causality, we must posit some first uncaused causal power (Transcendental Freedom), while the antithesis denies anything but mechanistic causality. Here, then, the debate is the standard (though in this case, the specifically cosmological) dispute between freedom and determinism. Finally, in the fourth antinomy, the requirement for a necessary being is pitted against its opposite. The thesis position argues for a necessary being, whereas the antithesis denies that there is any such being.
