Idealism in philosophy, also known as philosophical idealism or metaphysical idealism, is the set of metaphysical perspectives asserting that, most fundamentally, reality is equivalent to mind, spirit, or consciousness; that reality is entirely a mental construct; or that ideas are the highest form of reality or have the greatest claim to being considered "real". The radical latter view is often first credited to the Ancient Greek philosopher Plato as part of a theory now known as Platonic idealism. Other than in some Western philosophy, idealism also appears in some Indian philosophy, namely in Vedanta, one of the orthodox schools of Hindu philosophy, and in some streams of Buddhism.
Political philosophy or political theory is the philosophical study of government, addressing questions about the nature, scope, and legitimacy of public agents and institutions and the relationships between them. Its topics include politics, liberty, justice, property, rights, law, and the enforcement of laws by authority: what they are, if they are needed, what makes a government legitimate, what rights and freedoms it should protect, what form it should take, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown, if ever.
Secularism is the principle of seeking to conduct human affairs based on naturalistic considerations, uninvolved with religion.
John Bordley Rawls was an American moral, legal 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 was presented by President Bill Clinton in recognition of how his works "revived the disciplines of political and ethical philosophy with his argument that a society in which the most fortunate help the least fortunate is not only a moral society but a logical one".
German philosophy, meaning philosophy in the German language or philosophy by German people, in its diversity, is fundamental for both the analytic and continental traditions. It covers figures such as Gottfried Wilhelm Leibniz, Immanuel Kant, Georg Wilhelm Friedrich Hegel, Karl Marx, Friedrich Nietzsche, Martin Heidegger, Ludwig Wittgenstein, the Vienna Circle, and the Frankfurt School, who now count among the most famous and studied philosophers of all time. They are central to major philosophical movements such as rationalism, German idealism, Romanticism, dialectical materialism, existentialism, phenomenology, hermeneutics, logical positivism, and critical theory. The Danish philosopher Søren Kierkegaard is often also included in surveys of German philosophy due to his extensive engagement with German thinkers.
Jorge Agustín Nicolás Ruiz de Santayana y Borrás, known in English as George Santayana, was a Spanish-American philosopher, essayist, poet, and novelist. Born in Spain, Santayana was raised and educated in the US from the age of eight and identified himself as an American, although he always retained a valid Spanish passport. At the age of 48, Santayana left his position at Harvard and returned to Europe permanently.

Platonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary Platonists do not necessarily accept all doctrines of Plato. Platonism had a profound effect on Western thought. In its most basic fundamentals, Platonism affirms the existence of abstract objects, which are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on. Philosophers who affirm the existence of abstract objects are sometimes called Platonists; those who deny their existence are sometimes called nominalists. The terms "Platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object.

Metaphysical naturalism is a philosophical worldview which holds that there is nothing but natural elements, principles, and relations of the kind studied by the natural sciences. Methodological naturalism is a philosophical basis for science, for which metaphysical naturalism provides only one possible ontological foundation. Broadly, the corresponding theological perspective is religious naturalism or spiritual naturalism. More specifically, metaphysical naturalism rejects the supernatural concepts and explanations that are part of many religions.

The Realms of Being (1942) is the last major work by Spanish-American philosopher George Santayana. Along with Scepticism and Animal Faith and The Life of Reason, it is his most notable work; the first two works concentrate primarily on epistemology and ethics respectively, whereas The Realms of Being is mainly a work in the field of ontology.

American philosophy is the activity, corpus, and tradition of philosophers affiliated with the United States. The Internet Encyclopedia of Philosophy notes that while it lacks a "core of defining features, American Philosophy can nevertheless be seen as both reflecting and shaping collective American identity over the history of the nation". The philosophy of the Founding Fathers of the United States is largely seen as an extension of the European Enlightenment. A small number of philosophies are known as American in origin, namely pragmatism and transcendentalism, with their most prominent proponents being the philosophers William James and Ralph Waldo Emerson respectively.

Scottish philosophy is a philosophical tradition created by philosophers belonging to Scottish universities. Although many philosophers such as Francis Hutcheson, David Hume, Thomas Reid, and Adam Smith are familiar to almost all philosophers it was not until the 19th century that the notion of 'Scottish philosophy' became recognized and held to high regard on an international level. In the 20th century, however, this tradition declined as Scottish educated philosophers left for England.
