Problem: Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for our earth will find this hopeful

Problem: Fascinating roller coaster to discovery . Andrew Solomon is a science writer who has taken the risky step of telling the vast, intriguing story of a deeply personal condition in the first person - which means that we follow him on an extraordinary roller coaster ride toward self discovery and healing (Solomon suffers very serious depression and tries all manner of "cures" including a death-wish desire to contract AIDS, and bizarre tribal rites in Africa) while also tracing the long tortuous history (and geography) of Depression as a subject. Our understanding of Depression, Solomon lucidly reveals, has been the subject of a centuries-long tug of war between two mindsets: those who see it as a chemical condition, and those who see it as a psychological (ie emotional) condition. As the history of civilisation veers between rational and romantic eras, so too has the understanding and treatment of Depression. Is it any wonder that a modern sufferer is torn between the talk-therapies and the chemical therapies such as Prozac? Andrew Solomon comes down with an argument that both therapies are flipsides of the same whole - and that both have a role to play as sufferers seek escape from the bottomless black abyss. On the way he covers related subjects including Depression and suicide and Depression and creativity - and, this is the miracle of his writing and a tribute to his approach - the subject matter comes over as fascinating rather than gruelling. If you are a sufferer, or live with one - or simply wish to know better how the human mind really works, this volume is pretty compelling. One of the best pieces of advice that Andrew Solomon cites is from a Greek philosopher who, more than 2000 years ago suggested that sufferers enjoy good wine and food, and surround themselves with good friends. A humane and enormously rich piece of science writing
Solution:
POS
