Essential reading for Nietzsche's early etymological insights into the genealogy of the Greek word "sophos", which we associate today with theoretical or technical wisdom (techne), whereas according to him it first connoted refinement and rarity of discernment and taste, and whose usage is first noted with regard to kings, artists, and then philosophers, so as to suggest his hypothesis as laid out in the later works, notably Genealogy of Morals, The Gay Science, and Twilight of the Idols, that philosophical inquiry represents a kind of risk of fermentation of culture and decadence of sovereign values. Excellent introduction by the editor also with regard to Nietzsche's academic crisis with respect to the scandalous reception of his Birth of Tragedy, after which these lectures were supposedly given, in a kind of "back to basics", return-to-philology, and return-to-academia, approach to ancient philosophy, but whose prejudices clearly surface such as in the above mentioned instances, but especially in his staunch defense and exultation of Heraclitus as the sovereign thinker par excellence, in the face of contemporary prejudice that could not make sense of the notion that fire, as divine principle, is the sovereign force, not human consciousness, nor a stoic and conscious divinity in a poise of disinterested contemplation as the Kantian ideal would have it. In sum, a provocative set of lectures on ancient philosophy by the man arguably responsible for the rediscovery of the ancient Greeks in the late 19th century himself. The introduction also serves as a guideline for following Nietzsche's scholarship into the skeptical strains of Democritus, which foreshadows Nietzsche's foray into a skepticism skeptical of itself, not unlike the skeptics of Plato's Third Academy, except that Nietzsche emerges as a thinker who synthesizes the skepticism of skepticism itself, or the negation of the negation (or, the suspension of the suspension, to differentiate it from Hegelian negation), as pure affirmation, as we see beginning with his mature works, notably The Gay Science, Beyond Good and Evil, and especially Thus Spoke Zarathustra.
