Peter Singer

More often there's a compromise between ethics and expediency.

We should aim for our children to be good people, and to live ethical lives that manifest concern for others as well as for themselves.

The price we are willing to pay for safety cannot be infinite. It is distasteful to put a price on human life, but the more we spend on safety, the less we will have for our other goals.

We are looking for highly technical, enthusiastic and capable entrepreneurs who have a healthy disregard for the impossible, and that's not always easy to find.

The ego is nothing other than the focus of conscious attention.

I have no neighbours other than animals and Joshua Trees.
