Context

“But abstraction and the use of terms to record what is abstracted put the net value of individual experience at the permanent disposal of mankind. No one can foresee in detail when or how it may be of further use. The man of science in developing his abstractions is like a manufacturer of tools who does not know who will use them nor when. But intellectual tools are indefinitely more flexible in their range of adaptation than other mechanical tools. Generalization is the counterpart of abstraction. It is the functioning of an abstraction in its application to a new concrete experience,—its extension to clarify and direct new situations.” source
