“the great world, so far as we know it from philosophy of nature, is neither good nor bad, and is not concerned to make us happy or unhappy. All such philosophies spring from self-importance, and are best corrected by a little astronomy.”

“They haven’t an idea what happiness is; they don’t know that without our love, for us there is neither happiness nor unhappiness—no life at all”

“To read these books, in this way, as an exercise in self-knowledge, carries certain risks. Risks that are both personal and political. Risks that every student of Political Philosophy has known. These risks spring from the fact that philosophy teaches us, and unsettles us, by confronting us with what we already know. There is an irony: the difficulty of this course consists in the fact that it teaches what you already know. It works by taking what we know from familiar unquestioned settings, and making it strange. [...] Philosophy estranges us from the familiar, not by supplying new information, but by inviting and provoking a new way of seeing.But, and here is the risk, once the familiar turns strange, it is never quite the same again. Self-knowledge is like lost innocence; however unsettling you find it, it can never be 'unthought' or 'unknown'. What makes this enterprise difficult, but also revetting, is that Moral and Political Philosophy is a story, and you don't know where the story would lead, but you do know that the story is about You.”

“An excellent plumber is infinitely more admirable than an incompetent philosopher. The society which scorns excellence in plumbing because plumbing is a humble activity, and tolerates shoddiness in philosophy because it is an exalted activity, will have neither good plumbing nor good philosophy. Neither its pipes nor its theories will hold water.”

“Time heals. No, it doesn't. At best, time is the great leveler, sweeping us all into coffins. We find ways to distract ourselves from the pain. Time is neither scalpel nor bandage. It is indifferent. Scar tissue is not a good thing. It is merely the wound's other face.”

“No other life forms know they are alive, and neither do they know they will die. This is our curse alone. Without this hex upon our heads, we would never have withdrawn as far as we have from the natural—so far and for such a time that it is a relief to say what we have been trying with our all not to say: We have long since been denizens of the natural world. Everywhere around us are natural habitats, but within us is the shiver of startling and dreadful things. Simply put: We are not from here. If we vanished tomorrow, no organism on this planet would miss us. Nothing in nature needs us.”
