Bertrand Arthur William Russell, 3rd Earl Russell, was a British philosopher, logician, mathematician, historian, writer, essayist, social critic, political activist, and Nobel laureate. At various points in his life, Russell considered himself a liberal, a socialist and a pacifist, although he also confessed that his skeptical nature had led him to feel that he had "never been any of these things, in any profound sense." Russell was born in Monmouthshire into one of the most prominent aristocratic families in the United Kingdom.
Friedrich Wilhelm Nietzsche was a German philosopher, cultural critic, composer, poet, philologist, and Latin and Greek scholar whose work has exerted a profound influence on Western philosophy and modern intellectual history. He began his career as a classical philologist before turning to philosophy. He became the youngest ever to hold the Chair of Classical Philology at the University of Basel in 1869 at the age of 24. Nietzsche resigned in 1879 due to health problems that plagued him most of his life; he completed much of his core writing in the following decade. In 1889 at age 44, he suffered a collapse and afterward, a complete loss of his mental faculties. He lived his remaining years in the care of his mother until her death in 1897 and then with his sister Elisabeth Förster-Nietzsche. Nietzsche died in 1900.
Georg Wilhelm Friedrich Hegel was a German philosopher and an important figure of German idealism. He achieved wide recognition in his day and—while primarily influential within the continental tradition of philosophy—has become increasingly influential in the analytic tradition as well. Although Hegel remains a divisive figure, his canonical stature within Western philosophy is universally recognized.
Immanuel Kant was an influential German philosopher. In his doctrine of transcendental idealism, he argued that space, time and causation are mere sensibilities; "things-in-themselves" exist, but their nature is unknowable. In his view, the mind shapes and structures experience, with all human experience sharing certain structural features. He drew a parallel to the Copernican revolution in his proposition that worldly objects can be intuited a priori ('beforehand'), and that intuition is therefore independent from objective reality. Kant believed that reason is the source of morality, and that aesthetics arise from a faculty of disinterested judgment. Kant's views continue to have a major influence on contemporary philosophy, especially the fields of epistemology, ethics, political theory, and post-modern aesthetics.
Ludwig Josef Johann Wittgenstein was an Austrian-British philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language.
A philosopher is someone who practices philosophy, which involves rational inquiry into areas that are outside either theology or science. The term "philosopher" comes from the Ancient Greek, φιλόσοφος (philosophos), meaning "lover of wisdom". The coining of the term has been attributed to the Greek thinker Pythagoras.
Robert Nozick was an American philosopher. He held the Joseph Pellegrino University Professorship at Harvard University, and was president of the American Philosophical Association. He is best known for his books Philosophical Explanations (1981), which included his counterfactual theory of knowledge, and Anarchy, State, and Utopia (1974), a libertarian answer to John Rawls' A Theory of Justice (1971), in which Nozick also presented his own theory of utopia as one in which people can freely choose the rules of the society they enter into. His other work involved ethics, decision theory, philosophy of mind, metaphysics and epistemology. His final work before his death, Invariances (2001), introduced his theory of evolutionary cosmology, by which he argues invariances, and hence objectivity itself, emerged through evolution across possible worlds.
Taking Children Seriously (TCS) is a parenting movement and educational philosophy whose central idea is that it is possible and desirable to raise and educate children without either doing anything to them against their will, or making them do anything against their will.
William Payne Alston was an American philosopher. He made influential contributions to the philosophy of language, epistemology, and Christian philosophy. He earned his Ph.D. from the University of Chicago and taught at the University of Michigan, Rutgers University, University of Illinois, and Syracuse University.
John Bordley Rawls was an American moral and political philosopher in the liberal tradition. Rawls received both the Schock Prize for Logic and Philosophy and the National Humanities Medal in 1999, the latter presented by President Bill Clinton, in recognition of how Rawls's work "helped a whole generation of learned Americans revive their faith in democracy itself."
Christian Wolff was a German philosopher. Wolff was the most eminent German philosopher between Leibniz and Kant. His main achievement was a complete oeuvre on almost every scholarly subject of his time, displayed and unfolded according to his demonstrative-deductive, mathematical method, which perhaps represents the peak of Enlightenment rationality in Germany.
Ernest André Gellner was a British-Czech philosopher and social anthropologist described by The Daily Telegraph, when he died, as one of the world's most vigorous intellectuals, and by The Independent as a "one-man crusader for critical rationalism".

Hans Reichenbach was a leading philosopher of science, educator, and proponent of logical empiricism. He was influential in the areas of science, education, and of logical empiricism. He founded the Gesellschaft für empirische Philosophie in Berlin in 1928, also known as the “Berlin Circle”. Carl Gustav Hempel, Richard von Mises, David Hilbert and Kurt Grelling all became members of the Berlin Circle. He authored The Rise of Scientific Philosophy. In 1930, Reichenbach and Rudolf Carnap became editors of the journal Erkenntnis (Knowledge). He also made lasting contributions to the study of empiricism based on a theory of probability; the logic and the philosophy of mathematics; space, time, and relativity theory; analysis of probabilistic reasoning; and quantum mechanics.
Dewi Zephaniah Phillips, known as D. Z. Phillips, Dewi Z, Dizzy, or simply DZ, was a Welsh philosopher. He was a leading proponent of Wittgensteinian philosophy of religion.

Philosophy is the study of general and fundamental concerns such as existence, knowledge, matter, values, reason, mind, and language. The term was probably coined by Pythagoras. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? Philosophers also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust? Do humans have free will?
Stoicism is a school of Hellenistic philosophy founded by Zeno of Citium in Athens in the early 3rd century BC. While Stoic physics are largely drawn from the teachings of the philosopher Heraclitus, they are heavily influenced by certain teachings of Socrates. Stoicism is predominantly a philosophy of personal ethics informed by its system of logic and its views on the natural world. According to its teachings, as social beings, the path to happiness for humans is found in accepting the moment as it presents itself, by not allowing oneself to be controlled by the desire for pleasure or fear of pain, by using one's mind to understand the world and to do one's part in nature's plan, and by working together and treating others fairly and justly.
Socrates was a classical Greek (Athenian) philosopher credited as one of the founders of Western philosophy, and as being the first moral philosopher, of the Western ethical tradition of thought. An enigmatic figure, he made no writings, and is known chiefly through the accounts of classical writers writing after his lifetime, particularly his students Plato and Xenophon. Other sources include the contemporaneous Antisthenes, Aristippus, and Aeschines of Sphettos. Aristophanes, a playwright, is the only source to have written during his lifetime.
