• My mother taught me that the highest forms of understanding that we can achieve are laughter and human compassion
  • Do not keep saying to yourself, "But how can it be like that?" Nobody knows how it can be like that.
  • I don't believe in the idea that there are a few peculiar people capable of understanding math,
    and the rest of the world is normal.
  • You see, one thing is, I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here... I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell. It doesn't frighten me.
  • Science is like sex. Sometimes something useful comes of it, but that's not why anyone really does it
  • Never ascribe to malice that which can be adequately explained by stupidity
