--- Philosopher Thomas Nagel, The View From Nowhere, Oxford University Press 1989, Introduction, p. 9 (Google Books)
In context: The right attitude in philosophy is to accept aims that we can achieve only fractionally and imperfectly, and cannot be sure of achieving even to that extent. It means in particular not abandoing the pursuit of truth, even though if you want the truth rather than merely something to say, you will have a good deal less to say.
