  This set of forms was transferred to an individual in the process of socialization. When we bring a layperson to a laboratory and we ask her to describe a course of scientific experiments, professionals will find out immediately that she is not able to do this. She will surely create a long description and bring up a lot of unimportant or accidental details, but she will not pay attention to what is important from a scientist’s point of view. “If we wanted necessarily to render his experience in words, the most appropriate slogan would be: ‘I search’ or ‘I have a chaos’” (1935b). An expert sees differently than a layperson because she went through a special training during which she was familiarized with many examples—e.g. symptoms of a given disease and at the same time symptoms of other diseases (so with what X is and what X is not). At the same time she was equipped with a certain set of views on what that disease is, on the course of it, on how it is affected by external conditions etc. Thus, if the training process is successful a new member of a collective will directly see the same as what other members see “with their own eyes”. As Fleck states in the last sentence of (1935b), “’To see’ means: to recreate, at a suitable moment, a picture created by the mental collective to which one belongs”.
