Today's argumentation comes to the heart, not only of the lawyer's argument, but of the difficulty in determining the emotional and conceptual facts of Grandjean's experience.

And even in the structure of his presentation--whether he intended to be ambiguous or not--we can see the logical holes, given our context of being able to envision a greater range of possible identities.
