“Acting responsibly is not a matter of strengthening our reason but of deepening our feelings for the welfare of others.”

“Nevertheless we are free individuals, and this freedom condemns us to make choices throughout our lives. There are no eternal values or norms we can adhere to, which makes our choices even more significant. Because we are totally responsible for everything we do. Sartre emphasized that man must never disclaim the responsibility for his actions. Nor can we avoid the responsibility of making our own choices on the grounds that we "must" go to work, or we "must" live up to certain middle-class expectations regarding how we should live. Those who thus slip into the anonymous masses will never be other than members of the impersonal flock, having fled from themselves into self-deception. On the other hand our freedom obliges us to make something of ourselves, to live "authentically" or "truly".”

“It is by no means certain that we advance our philosophical quest by reading Plato or Aristotle. It may increase our knowledge of history but not of the world.”

“It is different for us mortals. We are the ones who become old and grey. We are the ones who become worn at the seams and disappear. But not our dreams. They can live on in other people even after we have gone.”

“I'm more concerned, just as you used to be, with the world as a riddle than with the riddles in the world. I'm more concerned with natural than the supernatural. And I feel more wonder for our inscrutable brain than for all these loose anecdots about the 'extrasensory'.”

“Hume emphasized that the expectation of one thing following another does not lie in the things themselves, but in our mind. And expectation, as we have seen, is associated with habit. Going back to the child again, it would not have stared in amazement if when one billiard ball struck the other, both had remained perfectly motionless. When we speak of the 'laws of nature' or of 'cause and effect,' we are actually speaking of what we expect, rather than what is 'reasonable.' The laws of nature are neither reasonable nor unreasonable, they simply are. The expectation that the white billiard ball will move when it is struck by the black billiard ball is therefore not innate. We are not born with a set of expectations as to what the world is like or how things in the world behave. The world is like it is, and it's something we get to know”

“We can be hindered in our development and our personal growth by political conditions. Outer circumstances can constrain us. Only when we are free to develop our innate abilities can we live as free beings. But we are just as much determined by inner potential and outer opportunities as the Stone Age boy on the Rhine, the lion in Africa, or the apple tree in the garden.”
