This post will just be a short note about an observation regarding conditionals in propositional logic. I actually read about this in a logic textbook a long time ago, but I don’t remember which one exactly. Anyway, the observation is that two conditionals can be logically equivalent, but their converses are not logically equivalent. An example of this are the conditionals and . They are logically equivalent, as a truth table demonstrates, but their respective converses and are not logically equivalent. Another, perhaps more striking example, are these two conditionals: and . They are logically equivalent, but their respective converses and are not logically equivalent.
