 In what follows, I shall begin with a short summary of Mill’s contribution. Subsequently, and turning to the German scene, I shall briefly sketch what authors accused of psychologism said on the relationship between logic and psychology, before outlining Frege’s and Husserl’s arguments against them. I shall conclude by presenting a number of objections to Frege’s and Husserl’s anti-psychologism. Some of these objections come from Frege’s and Husserl’s contemporaries, others are of more recent origin.
