A Brilliant Analysis of the Black Man's Experience with Colonialism. A Scientific Analysis of the Black Psyche in a White World
Format: Paperback
This is a brilliant attempt of the era to scientifically analyze the black psyche in a white world. This book has far reaching effects on how colonialism was viewed to impact the black man in society and undoubtedly must have sparked a few revolutionary undertakings. This is not my first encounter with this book, I have had the opportunity to use it as sociological reference in 1981/82 and felt compelled that I would read it in its entirety some day. Now I can say I did and was more than satisfied. Fanon is a great writer of his times and beyond. I am tempted to say that this book should be read by all Black men and women however it is not an easy read because to me it is not a Novel (not a story book). As a student of History, Sociology, Psychology and Psychiatry I found it very delightful and relatively easy to follow. This Book is very powerful writings for the time when it was written, no wonder Fanon was dissuaded from using it as his Thesis for his Ph.D.. May his soul rest in peace but may his ideas live on. O my body always make me a man who questions?

An evocative poetic-critical reading of oppression, racism, colonialism
Format: Paperback
"I am black; I am in total fusion with the world, in sympathetic affinity with the earth, losing my id in the heart of the cosmos... I am black, not because of a curse, but because my skin has been able to capture all the cosmic effluvia. I am truly a drop of sun under the earth." (p. 27)~ Thus Fanon reaches into the experience and meaning of the black man's alienation. This alienation strikes in an essential sense--it stems from the denial of the black man's very flesh: "The black man is attacked for his corporeality. It is his tangible personality that is lynched. It is his actual being that is dangerous..." (142). The white man, who has been obsessed with eradicating the body out of collective consciousness for millennia, now associates this abjected domain of the body with the black man, and constructs it as the essential evil Other. The white man does this because he is insecure--he does this out of hatred, a hatred that he works to cultivate, that consumes his time and energy. The white man is dehumanized. Projecting his fears onto the black man, the white man shirks his responsibility to acknowledge his guilt (83) in instrumentalizing the black man (206). Even though this work was written over 50 years ago in a literal colony of Europe, sadly it remains only too relevant in the United States today as a condition between people that allegedly have the same legal and human rights. This is largely made possible by the many ever-so-casual-racists (who vehemently deny they are racist)--people who, for example, complain about affirmative action as unfair to them personally (nevermind history and generations of enslavement and stolen opportunities). Fanon writes, "outside university circles there is an army of fools... Granted, these fools are the product of a psychological-economic substructure. But that does not get us anywhere" (18). An education for racial tolerance from which we are sadly very far removed is necessary for moving towards a world of love.

Format: Kindle
Good book, this isn't my favorite (Wretched of the Earth continues to be) but it gives a good account of the effects of colonialism on people's psyche. Fanon masterfully demonstrates how violence is practiced on the minds and bodies of those on the receiving end of colonialism. He digs deep into how the ideology of whiteness as 'pure' and 'good' are, for one, deeply flawed, but more importantly, these false beliefs are incredibly damaging to humanity as a whole. Although it's a good book, I found some serious flaws with some of his arguments but I still think it was worth the read.
