Youth, like love, has no homeland. Rather, it is the common crown of humanity. In these chapters, I have intended to talk about a group of the immortal youth of nations, of different horizons, races, and times. Among them was the man of politics, the man of letters, and the girl of war - Joan of Arc - who took on men's clothing, and the time varied between them, from the era of ancient Greek civilization to the world of Egyptian politics at the beginning of the twentieth century.. The author - may God have mercy on him - returned to some of his chapters with amendments and corrections, and perhaps the appearance of this new edition will fulfill the wishes of those who expressed their desire to reprint the chapters that were first published under the title "The Geniuses of Youth."
