“A philosophical thought is not supposed to be impervious to all criticism; this is the error Whitehead describes of turning philosophy into geometry, and it is useful primarily as a way of gaining short-term triumphs in personal arguments that no one else cares (or even knows) about anyway. A good philosophical thought will always be subject to criticisms (as Heidegger’s or Whitehead’s best insights all are) but they are of such elegance and depth that they change the terms of debate, and function as a sort of “obligatory passage point” (Latour’s term) in the discussions that follow.Or in other words, the reason Being and Time is still such a classic, with hundreds of thousands or millions of readers almost a century later, is not because Heidegger made “fewer mistakes” than others of his generation. Mistakes need to be cleaned up, but that is not the primary engine of personal or collective intellectual progress.”

“Future generations may or may not judge Wittgenstein to be one of the great philosophers. Even if they do not, however, he is sure always to count as one of the great personalities of philosophy. From our perspective it is easy to mistake one for the other; which he is time will tell.”

“Anyway, maybe there weren't any solutions. Human society, corpses and rubble. It never learned, it made the same cretinous mistakes over and over, trading short-term gain for long-term pain.”

“Widespread intellectual and moral docility may be convenient for leaders in the short term, but it is suicidal for nations in the long term. One of the criteria for national leadership should therefore be a talent for understanding, encouraging, and making constructive use of vigorous criticism.”

“A person of your century: Great persons are of their time. Not all were born into a period worthy of them, and many so born failed to benefit by it. Some merited a better century, for all that is good does not always triumph. Fashions have their periods and even the greatest virtues, their styles. But the philosopher, being ageless, has one advantage: Should this not prove the right century, many to follow will.”

“I'll take an earnest person over a hip person every time, because hip is short term. Earnest is long term.”

“The truth, he thought, has never been of any real value to any human being - it is a symbol for mathematicians and philosophers to pursue. In human relations kindness and lies are worth a thousand truths.”
