At this point in Friedrich Nietzsche's life, as it is reflected on "Beyond Good and Evil", he viewed certain types of philosophy as counterproductive, such as universalism, or the idea that some specific truths could be applied across all ages, to all people, in all societies. Instead, he believed that it depends on the time, situation, and perspective to figure out when personal sacrifice is worth the public good.
Friedrich Nietzsche was a German doctor and philosopher that was born in the mid-19th century. His book, "Beyond Good and Evil" was one of the last books he wrote, during the period of 1886 to 1888 - a two year period when he authored a total of seven books. "Beyond Good and Evil" became one of the best-known in that group and is commonly viewed as a book written by a philosopher for philosophers.
