“The clash of civilizations is nothing but a clash of different myths.”

"The Clash of Civilizations?," in Foreign Affairs (1993)
Context: It is my hypothesis that the fundamental source of conflict in this new world will not be primarily ideological or primarily economic. The great divisions among humankind and the dominating source of conflict will be cultural. Nation-states will remain the most powerful actors in world affairs, but the principal conflicts of global politics will occur between nations and groups of different civilizations. The clash of civilizations will dominate global politics. The fault lines between civilizations will be the battle lines of the future.

Context: The futures of both peace and Civilization depend upon understanding and cooperation among the political, spiritual, and intellectual leaders of the world’s major civilizations. In the clash of civilizations, Europe and America will hang together or hang separately. In the greater clash, the global “real clash,” between Civilization and barbarism, the world’s great civilizations, with their rich accomplishments in religion, art, literature, philosophy, science, technology, morality, and compassion, will also hang together or hang separately. In the emerging era, clashes of civilizations are the greatest threat to world peace, and an international order based on civilizations is the surest safeguard against world war.

Original: Votre œil bleu du nord regardait attentivement les tableaux pendus aux murs. J’eus comme le pressentiment d’une révolte : tout un choc entre votre civilisation et ma barbarie. Civilisation dont vous souffrez. Barbarie qui est pour moi un rajeunissement.

International Business and Leadership Symposium address

Frankfurt Book Fair speech (2003)
Context: All modern wars, even when their aims are the traditional ones, such as territorial aggrandizement or the acquisition of scarce resources, are cast as clashes of civilizations — culture wars — with each side claiming the high ground, and characterizing the other as barbaric. The enemy is invariably a threat to "our way of life," an infidel, a desecrator, a polluter, a defiler of higher or better values. The current war against the very real threat posed by militant Islamic fundamentalism is a particularly clear example.

Know Thyself (1881)
Context: What "Conservatives," "Liberals" and "Conservative-liberals," and finally "Democrats," "Socialists," or even "Social-democrats" etc., have lately uttered on the Jewish Question, must seem to us a trifle foolish; for none of these parties would think of testing that "Know thyself" upon themselves, not even the most indefinite and therefore the only one that styles itself in German, the "Progress"-party. There we see nothing but a clash of interests, whose object is common to all the disputants, common and ignoble: plainly the side most strongly organised, i. e. the most unscrupulous, will bear away the prize. With all our comprehensive State- and National-Economy, it would seem that we are victims to a dream now flattering, now terrifying, and finally asphyxiating: all are panting to awake therefrom; but it is the dream's peculiarity that, so long as it enmeshes us, we take it for real life, and fight against our wakening as though we fought with death. At last one crowning horror gives the tortured wretch the needful strength: he wakes, and what he held most real was but a figment of the dæmon of distraught mankind.
We who belong to none of all those parties, but seek our welfare solely in man's wakening to his simple hallowed dignity; we who are excluded from these parties as useless persons, and yet are sympathetically troubled for them, — we can only stand and watch the spasms of the dreamer, since no cry of ours can pierce to him. So let us save and tend and brace our best of forces, to bear a noble cordial to the sleeper when he wakes, as of himself he must at last.
