Abstract
What is the meaning of if … then clauses? More than 2000 year ago, Philo argued for what we now call material implication. And Chrysippos fought for what we now call strict implication. In modern times, G. Frege argued for material implication again. And so did C. I. Lewis for strict implication. Philo and Chrysippos, Frege and Lewis defended their ideas, found followers and died.
