The teacher's approach to such problems might start from three assumptions: (a) the teacher should be concerned with how science fits into the larger framework of life, and the student should raise questions about the meaning of what he studies and its relation to other fields; (b)
controversial questions can be treated, not in a spirit of indoctrination, but with an emphasis
on asking questions and helping students think through assumptions and implications; an effort should be made to present
viewpoints other than one's own as fairly as possible, respecting the integrity of the student by avoiding undue imposition of the lecturer's beliefs; (c) presuppositions inevitably enter the classroom presentation of many
subjects, so that a
viewpoint frankly and explicitly recognized may be less dangerous than one which is hidden and assumed not to exist.
