Men talk of nature as an abstract thing, and lose sight of what is natural while they do so.

 - Charles Dickens

If you have a large number of unrelated ideas, you have to get quite a distance away from them to get a view of all of them and this is the role of abstraction. If you look at each too closely you see too many details. If you get far away things may appear simpler because you can only see the large, broad outlines; you do not get lost in petty details.

 - John Kemeny

The power of using abstractions is the essence of intellect, and with every increase in abstraction the intellectual triumphs of science are enhanced.

 - Bertrand Russell
