Class (philosophy)

In at least one source, a "class" is a set in which an individual member can be recognized in one or both of two ways: a) it is included in an extensional definition of the whole set (a list of set members) b) it matches an intensional definition of one set member. By contrast, a "type" is an intensional definition; it is a description that is sufficiently generalized to fit every member of a set.

Philosophers sometimes distinguish classes from types and kinds. We can talk about the class of human beings, just as we can talk about the type (or natural kind), human being, or humanity. How, then, might classes differ from types? One might well think they are not actually different categories of being, but typically, while both are treated as abstract objects, classes are not usually treated as universals, whereas types usually are. Whether natural kinds ought to be considered universals is vexed; see natural kind.

There is, in any case, a difference in how we talk about types or kinds. We say that Socrates is a token of a type, or an instance of the natural kind, human being. But notice that we say instead that Socrates is a member of the class of human beings. We would not say that Socrates is a "member" of the type or kind, human beings. Nor would we say he is a type (or kind) of a class. He is a token (instance) of the type (kind). So the linguistic difference is: types (or kinds) have tokens (or instances); classes, on the other hand, have members.

Philosophy

Philosophy is the study of the general and fundamental nature of reality, existence, knowledge, values, reason, mind, and language. The Ancient Greek word φιλοσοφία (philosophia) was probably coined by Pythagoras and literally means "love of wisdom" or "friend of wisdom". Philosophy has been divided into many sub-fields. It has been divided chronologically (e.g., ancient and modern); by topic (the major topics being epistemology, logic, metaphysics, ethics, and aesthetics); and by style (e.g., analytic philosophy).

As a method, philosophy is often distinguished from other ways of addressing such problems by its questioning, critical, generally systematic approach and its reliance on rational argument. As a noun, the term "philosophy" can refer to any body of knowledge. Historically, these bodies of knowledge were commonly divided into natural philosophy, moral philosophy, and metaphysical philosophy. In casual speech, the term can refer to any of "the most basic beliefs, concepts, and attitudes of an individual or group," (e.g., "Dr. Smith's philosophy of parenting").

Oprah Winfrey

Oprah Gail Winfrey, born January 29, 1954, is an American media proprietor, talk show host, actress, producer, and philanthropist. She is best known for her talk show The Oprah Winfrey Show, which was the highest-rated program of its kind in history and was nationally syndicated from 1986 to 2011. Dubbed the "Queen of All Media", she has been ranked the richest African-American of the 20th century, the greatest black philanthropist in American history, and is now North America's first and only multi-billionaire Black. Several assessments regard her as the most influential woman in the world. In 2013, she was awarded the Presidential Medal of Freedom by President Barack Obama and honorary doctorate degrees from Duke and Harvard.

Winfrey was born into poverty in rural Mississippi to a teenage single mother and later raised in an inner-city Milwaukee neighborhood. She has stated that she was molested during her childhood and early teens and became pregnant at 14; her son died in infancy. Sent to live with the man she calls her father, a barber in Tennessee, Winfrey landed a job in radio while still in high school and began co-anchoring the local evening news at the age of 19. Her emotional ad-lib delivery eventually got her transferred to the daytime-talk-show arena, and after boosting a third-rated local Chicago talk show to first place, she launched her own production company and became internationally syndicated.
