“What of men? I can't think of anything more banal. I have no doubt — no doubt whatsoever — that once it has obtained the means to do so, the species will wipe itself off the face of the earth. There is no mystery to it; it is our nature. Oh, one might delve into the particulars, but really, what can we say about the species that invented murder? What can we say?”

“When we use these words and we talk about plants having a strategy to do this or wanting this or desiring this, we’re being metaphorical obviously. I mean, plants do not have consciousness. But, this is a fault of our own vocabulary. We don’t have a very good vocabulary to describe what others species do to us, because we think we’re the only species that really does anything.”

“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 certainty about different things, but I'm 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, and what the question might mean. I might think about it a little bit and if I can't figure it out, then I go on to something else, but I don't have to know an answer, I don't feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is so far as I can tell. It doesn't frighten me.”

“He doubted her. You must never doubt the one you love.But they might not be telling the truth.Never mind that. You tell them the truth.What do you mean?You can't be another person's honesty, child, but you can be your own.So what should I say?When?When I love someone?You should say it.”

“We can't define anything precisely. If we attempt to, we get into the paralysis of thought that comes to philosophers... one saying to the other: you don't know what you are talking about! The second one says: what do you mean by talking? What do you mean by you? What do you mean by know?”

“We work in the dark—we do what we can—we give what we have. Our doubt is our passion, and our passion is our task. The rest is the madness of art.”
