Seeing, thought and expression are rendered possible only by the fact that our minds are always ready to compromise and to take the part for the whole.

Context

“His business is to supply those details which will most readily bring the whole before the mind along with them. He must not give too few, but it is still more imperative on him not to give too many. Seeing, thought and expression are rendered possible only by the fact that our minds are always ready to compromise and to take the part for the whole. We associate a number of ideas with any given object, and if a few of the most characteristic of these are put before us we take the rest as read, jump to a conclusion and realise the whole. If we did not conduct our thought on this principle—simplifying by suppression of detail and breadth of treatment—it would take us a twelvemonth to say that it was a fine morning and another for the hearer to apprehend our statement.” source
