ABSTRACT
Being Jewish, I was brought up on the philosophy of "on the one hand we have ... but on the other hand ...", that is, a reluctance or incapacity to accept dogmas. As I became involved with seminars where trainees presented their observations on the first year of a baby's life, this attitude of mine proved to be not only justifiable, but central to teaching students to respect their interpretations of what they saw, but always to subject these impressions to a detailed and careful scrutiny.
