Writing (extra)

Considering the multitude of data that people in our contemporary society need to remember, a certain amount of notetaking and information deposited in books is unavoidable. 

But the tendency away from remembering is growing beyond all sensible proportions.

One can easily and best observe in oneself that writing thing down diminishes one's power of remembering, but some typical examples may prove helpful. 

An everyday example occurs in stores.

Today a salesclerk will rarely do a simple addition of two or three items in hi or her head, but will immediately use a machine. 

the classroom provides another example.

Teachers can observe that the students who carefully write down every sentence of the lecture will understand and remember less than the student who trusted their capacity to understand and, hence, remember at least the essentials.
