Nineteen thousand children [are] dying every day. Does it really matter that we're not walking past them in the street? Does it really matter that they're far away? I don't think it does make a morally relevant difference.

Becoming a vegan is a sure way of completely avoiding participation in the abuse of farmed animals. Vegans are a living demonstration of the fact that we do not need to exploit animals for food.

History is not going to look kindly on us if we just keep our head in the sand on armed autonomous robotics issue because it sounds too science fiction.

My view is different from this, only to the extent that if a decision is taken, by the parents and doctors, that it is better that a baby should die, I believe it should be possible to carry out that decision, not only by withholding or withdrawing life-support - which can lead to the baby dying slowly from dehydration or from an infection - but also by taking active steps to end the baby's life swiftly and humanely.

Scholars have long dreamed of a universal library containing everything that has ever been written.

Unfortunately for ethical egoism, the claim that we will all be better off if every one of us does what is in his or her own interest is incorrect. This is shown by what are known as "prisoner's dilemma" situations, which are playing an increasingly important role in discussions of ethical theory... At least on the collective level, therefore, egoism is self-defeating - a conclusion well brought out by Parfit in his aforementioned Reasons and Persons.
