The intrinsic dialectic in Gabriel Marcel’s thought seems to be describable in terms of alteration and doubling. That dialectic arises from the experience of wonder and of emotion; it articulates itself within a doubled consciousness which is both exclamative and interrogative. This consciousness perpetuates the original moment of alteration and doubling in the pairs characterizing Marcel’s speculative proposal: being-having, mystery-problem, transcendence-immanence, infinite-finite.
