“The lost moralities” is an application which includes a series of books by the writer: Tarek Ahmed Hassan. They are respectively called: “false balance”, “The age of wisdom”, “Good evil”, “Cultural oppression”, “The fingerprints of spirits” and “The lost moralities” The writer calls for the return to the human moralities stemming from ourselves, not those coming from abroad. Our humanitarian nature is good and the culture is what had spoiled it. The human being is born equipped with a solid biological moral basis. The principle of “the survival for the fittest” has evolved to “the survival for whoever has better moralities” long time before the civilization which we know. But some people wanted to survive at the expense of other people. So they fell from morality to power and imposed this on everyone. We have lost our moralities, then we went out looking for them, but we only found false merchandise wearing a religious or ideological dress. The result is the epidemic of the stumble, the false balance, the collective neurosis or the half of madness. The wise creature that has lost half of his mind on the day that he has lost his morals seems to be happy with the other half of his mind, which is still intact. But this situation can not last long. The enormous mental and physical abilities that have been endowed to human can not be separated from his moral evolution. If man continues to manipulate with moralities, he will use the same abilities to destroy himself and to destroy nature. The disaster can only be prevented by the return of the lost moralities.
