 Possibilism emerges from the question of the truth conditions for such possibilities, the question of what it is about reality that accounts for their truth value. The assertion that there are tigers, for example, is true because reality, in fact, contains tigers; the assertion that someone has free soloed the Dawn Wall or is Bergoglio’s child is false because reality, in fact, contains no such things. But what accounts for their possibility? That is, what is it about reality that accounts for the truth of  (1)  and  (2)?
