Even after almost four decades Colin Wilson's work still has a refreshing quality to it. In it he presents his readers with a novel approach to alienation and creativity. Beware though, this is not just another book on people who feel alienated or suffer pangs of Weltschmerz, it is about genuine 'outsiders', in Wilson's phrase someone who sees 'too much and too deep'. This distinction should be borne in mind.
The work presents several examples of classical outsiders, most of them failures according to the author, but there is also the occasional success story.
The book can be a bit long-winded at times, and Wilson does have a certain rhetoric tendency. Another fact that strikes me is that women are very thin on the ground in this study. This would perhaps have been less surprising had it been written, say, half a century earlier, but it should have been possible to find female outsiders too.
Nevertheless, this is a highly original and though-provoking work, which everyone with an interest in philsophy would do well to read.
