Temporal logic
Temporal logic is the discipline of applying logic to temporal mechanics.

While discussing time travel with Berlinghoff Rasmussen in 2368, Jean-Luc Picard noted that first year philosophy students asked questions relating to temporal logic such as "What if one of those lives I save down there is a child who grows up to be the next Adolf Hitler or Khan Singh?" He then pointed out that they were not in a classroom and that the situation they found themselves at Penthara IV in was not hypothetical, but real. ()
