We feel an affinity with a certain thinker because we agree with him; or because he shows us what we were already thinking; or because he shows us in a more articulate form what we were already thinking; or because he shows us what we were on the point of thinking; or what we would sooner or later have thought; or what we would have thought much later if we hadn’t read it now; or what we would have been likely to think but never would have thought if we hadn’t read it now; or what we would have liked to think but never would have thought if we hadn’t read it now.
