Answer that I'll offer: PURSUING WISDOM
There were many Greek philosophers, and their ideas were not all in agreement with each other. But in general, the Greek philosophers all agreed that pursuing wisdom is the most important thing in life. One of the earliest of Greek philosophers, Pythagoras (in the 6th century BC), is thought to have coined the term "philosopher." The report is that Pythagoras did not want to claim to be a wise man who already had great wisdom, but that he was a "lover of wisdom" who sought to be wise. In Greek, "philos" is a word for "love" and "sophia" is the word for wisdom. So a "philosopher" is a "lover of wisdom."
The great philosopher Socrates (5th century BC) was famous for saying, "The unexamined life is not worth living." He saw the goal of his life as constantly seeking wisdom -- and that what truly made him wise was recognizing how little he truly knew with certainty.
Other Greek philosophers like Plato and Aristotle and more followed in that tradition. They did not all agree on all the details of what the best pattern is for life in this world. But they did all seek wisdom as the most important thing in life.
I believe the correct answer to this would be A). Epidemics
<span>Despite being freed from slavery about 80 years before the end of World War II, African-Americans were still treated - often at best - as second class citizens in the southern states and discrimination was common in varying forms almost everywhere in the south (and, to a measure, in the northern states as well). While social change for African-Americans and other minorities came along rather slowly, it did eventually come (at least in part). President Truman famously - and quite forcefully and progressively for the time in the late 1940s - noted that "if the United States were to offer the peoples of the world a choice of freedom or enslavement it must correct the remaining imperfections in our practice of democracy." Beginning in the early 1950s states in both the north and the south established fair employment commissions, passed laws banning discrimination, and minority voter registrations began to rise throughout the country. In 1954, the Supreme Court case of Brown v. Board of Education paved the way for desegregation in all public schools. In the mid 1960s, President Johnson not only disliked injustice, he understood the international repercussions that came along with America’s perceived hypocrisy. In turn, he helped to pass The Civil Rights Act of 1964 that banned all forms of discrimination in public and a majority of private accommodations.</span>
