I think philosophers are probably quite jealous of science and this is why they come up with all this nonsense to try to show it’s not as reliable as people like to think it is. Look at how successful science is – philosophy is not successful – it’s achieved nothing

Statements to the effect that philosophy will enhance democracy and human rights are not incantations that if repeated enough will magic these results into existence. Teaching more philosophy in schools may well not have dramatic effects in opening people’s minds and promoting intercultural dialogue, and will certainly not have immediate ones.

My father really looked forward to reading my book and then was terribly disappointed when he found it was unreadable. One of the reader’s reports for the press when it was published said ‘This book is written ordinary English – there are no symbols, little of what could be called technical terminology – but this appearance is entirely misleading’.

The philosophical taste for put-downs seems to be giving way to an appetite for what you might call intellectual inclusion: a willingness to talk to other people, however foolish they are considered to be, in the hope of learning something from the conversation. For these reasons I think the place and time may be right for mending the rift between philosophy and the other arts.

If we are willing to accept that a large part of our shared knowledge of the world includes engineering knowledge, then we can conclude that a lot of our sophisticated knowledge is steadfast; that it has been, and will continue to be, developed and improved upon.

Socrates is anything but open-minded in his ideas about how life should be examined. In order to discover the truth, Socrates and his interlocutors need no information or fresh insight from outside themselves; they only need to find out which of their own ideas contradict one another. Socrates tests his prejudices against one another, but never thinks of throwing them all out, or trying a different methodology.

Some people clearly do think of humanism as being a kind of creed or value system. The first “humanist manifesto” published in 1933 talked of humanism as a “new religion”. Nowhere does this idea ring more true than at weekend meetings of Ethical Societies in chilly and austere halls which can resemble Methodist chapels or Christian Scientist temples. It’s hard to resist the cheap shot that a lot of what has passed for atheistical humanism has been a kind of non-conformism without the hymns.

“The most important thing I got out of my own experience with evil and the inhuman is that one should not live in bitterness, but rather with a sense of humanity. One should always try to find ways of remaining ethical in the face of evil and to look for the humanity in the inhuman.”

Illegal drugs are not inherently unclean, any more than alcohol, tobacco, or canola oil. All of these are simply chemicals that people choose to ingest for enjoyment, and that can harm our health if used to excess. Most of the sordid associations we have with illegal drugs are actually the product of the drug laws: it is because of the laws that drugs are sold on the black market, that Latin American crime bosses are made rich, that government officials are corrupted, and that drug users rob others to buy drugs.
