I ran into a quote by Karl R. Popper:
“A rationalist is simply someone for whom it is more important to learn than to be proved right; someone who is willing to learn from others - not by simply taking over another's opinions, but by gladly allowing others to criticize his ideas and by gladly criticizing the ideas of others”
I am thinking on the phrasal verb simply take over here. I know take over means gain control over, but it does not make an intact sense here? Look like here it mean only accept. What does simply take over mean here? Could you paraphrase the bolded?
