A propos this, philosopher Johannes Steizinger calls my attention to this remark of Hans Reichenbach’s in The Rise of Scientific Philosophy (p. 297):

Whoever wants to study ethics, therefore, should not go to the philosopher; he should live in the community of a group where life is made vivid by competing volitions, be it the group of a political party, or of a trade union, or of a professional organization, or of a ski club, or a group formed by common study in a classroom. There he will experience what it means to set his volitions against that of other persons and what it means to adjust oneself to group will. If ethics is the pursuit of volitions, it is also the conditioning of volitions through group environment.
