The Baconian method is the investigative method developed by Francis Bacon, one of the founders of modern science, and thus a first formulation of a modern scientific method. The method was put forward in Bacon's book Novum Organum (1620), or 'New Method', to replace the old methods put forward in Aristotle's Organon. It influenced the early modern rejection of medieval Aristotelianism.

Classical republicanism, also known as civic republicanism or civic humanism, is a form of republicanism developed in the Renaissance inspired by the governmental forms and writings of classical antiquity, especially such classical writers as Aristotle, Polybius, and Cicero. Classical republicanism is built around concepts such as liberty as non-domination, self-government, rule of law, property-based personality, anti-corruption, abolition of monarchy, civics, civil society, common good, civic virtue, civic participation, popular sovereignty, patriotism and mixed government.

Natural philosophy or philosophy of nature (from Latin philosophia naturalis) is the philosophical study of physics, that is, nature and the physical universe, while ignoring any supernatural influence. It was dominant before the development of modern science.

From the ancient world (at least since Aristotle) until the 19th century, natural philosophy was the common term for the study of physics (nature), a broad term that included botany, zoology, anthropology, and chemistry as well as what is now called physics. It was in the 19th century that the concept of science received its modern shape, with different subjects within science emerging, such as astronomy, biology, and physics. Institutions and communities devoted to science were founded. Isaac Newton's book Philosophiæ Naturalis Principia Mathematica (1687) (English: Mathematical Principles of Natural Philosophy) reflects the use of the term natural philosophy in the 17th century. Even in the 19th century, the work that helped define much of modern physics bore the title Treatise on Natural Philosophy (1867).

In Immanuel Kant's philosophy, a category (German: Categorie in the original or Kategorie in modern German) is a pure concept of the understanding (Verstand). A Kantian category is a characteristic of the appearance of any object in general, before it has been experienced (a priori). Following Aristotle, Kant uses the term categories to describe the "pure concepts of the understanding, which apply to objects of intuition in general a priori…" Kant further wrote about the categories: "They are concepts of an object in general, by means of which its intuition is regarded as determined with regard to one of the logical functions for judgments." The categories are the condition of the possibility of objects in general, that is, objects as such, any and all objects, not specific objects in particular. Kant enumerated twelve distinct but thematically related categories.

A priori ('from the earlier') and a posteriori ('from the later') are Latin phrases used in philosophy & linguistics to distinguish types of knowledge, justification, or argument by their reliance on experience. A priori knowledge is independent of any experience. Examples include mathematics, tautologies and deduction from pure reason. A posteriori knowledge depends on empirical evidence. Examples include most fields of science and aspects of personal knowledge.

The terms originate from the analytic methods found in Organon, a collection of works by Aristotle. Prior analytics (a priori) is about deductive logic, which comes from definitions and first principles. Posterior analytics (a posteriori) is about inductive logic, which comes from observational evidence.

Political decay is a political theory, originally described in 1965 by Samuel P. Huntington, which describes how chaos and disorder can arise from social modernization increasing more rapidly than political and institutional modernization. Huntington provides different definitions for political development and describes the forms of political decay according to the various definitions. Huntington focuses primarily on political development as modernization and institutionalization. However, he points to the different definitions of political development as being arbitrary ways to understanding the rise of political systems and the relationship between the political systems of different nations.

Political decay is a widespread ailment that affects every society. As Aristotle once noted, humans are inherently political beings (zōon politikon), but it is rare to find individuals who are truly honest in their political endeavors.

The 1st millennium BC, also known as the last millennium BC, was the period of time lasting from the years 1000 BC to 1 BC (10th to 1st centuries BC; in astronomy: JD 1356182.5 – 1721425.5). It encompasses the Iron Age in the Old World and sees the transition from the Ancient Near East to classical antiquity.

World population roughly doubled over the course of the millennium, from about 100 million to about 200–250 million after the birth of Jesus Christ and the establishment of the Julio-Claudian dynasty led by its founder Octavian.

Mixed government (or a mixed constitution) is a form of government that combines elements of democracy, aristocracy and monarchy, ostensibly making impossible their respective degenerations which are conceived in Aristotle's Politics as anarchy, oligarchy and tyranny. The idea was popularized during classical antiquity in order to describe the stability, the innovation and the success of the republic as a form of government developed under the Roman constitution.

Unlike classical democracy, aristocracy or monarchy, under a mixed government rulers are elected by citizens rather than acquiring their positions by inheritance or sortition (at the Greco-Roman time, sortition was conventionally regarded as the principal characteristic of classical democracy).

Politics (Πολιτικά, Politiká) is a work of political philosophy by Aristotle, a 4th-century BC Greek philosopher.

At the end of the Nicomachean Ethics, Aristotle declared that the inquiry into ethics leads into a discussion of politics. The two works are frequently considered to be parts of a larger treatise – or perhaps connected lectures – dealing with the "philosophy of human affairs". In Aristotle's hierarchical system of philosophy he considers politics, the study of communities, to be of higher priority than ethics, which concerns individuals.

Gertrude Elizabeth Margaret Anscombe FBA (/ˈænskəm/; 18 March 1919 – 5 January 2001), usually cited as G. E. M. Anscombe or Elizabeth Anscombe, was a British analytic philosopher. She wrote on the philosophy of mind, philosophy of action, philosophical logic, philosophy of language, and ethics. She was a prominent figure of analytical Thomism, a fellow of Somerville College, Oxford, and a professor of philosophy at the University of Cambridge.

Anscombe was a student of Ludwig Wittgenstein and became an authority on his work and edited and translated many books drawn from his writings, above all his Philosophical Investigations. Anscombe's 1958 article "Modern Moral Philosophy" introduced the term consequentialism into the language of analytic philosophy, and had a seminal influence on contemporary virtue ethics. Her monograph Intention (1957) was described by Donald Davidson as "the most important treatment of action since Aristotle". It is "widely considered a foundational text in contemporary philosophy of action" and has also had influence in the philosophy of practical reason."
