CR terms

Dennis suggested I create this discussion and tag @dirk-meulenbelt and @darren-wiebe.

Logan Chipkin has also suggested I get in contact with @darren-wiebe in regards to putting together a CR encyclopedia or something of the sort.

Historicism

The mistaken belief that history is governed by discoverable, large-scale "laws of history" or "powerful historical trends". This belief leads to the idea of unconditional historical prophecy, which is anti-rational and politically disastrous, as seen in the philosophies of Plato, Hegel, and Marx. It is contrasted with the "piecemeal" method of making specific, conditional predictions.

Political Holism

Synonymous with large-scale social engineering, this is the political program that follows from Historicism. It is the attempt to remodel an entire society from a central blueprint, based on a historicist prophecy of an "ideal" state. Popper argued this program is both violent and irrational. It is violent because it requires the suppression of all dissent to enact the central plan, and it is irrational because when an entire system is changed at once, it becomes impossible to trace the consequences of any single action, making it impossible to learn from mistakes.

Justificationism

The mistaken philosophical tradition holding that knowledge must be "justified" (i.e., proven, supported, or made probable) by appealing to an ultimate, infallible authority. Critical Rationalism identifies this entire approach as logically untenable, as any demand for justification leads to an inescapable logical trap known as the Münchhausen Trilemma: either an infinite regress (every justification needs a justification), circularity (the belief justifies itself), or dogmatism (the justification stops at a "self-evident" belief). Critical Rationalism is a non-justificationist philosophy; it rejects the entire quest for justified, certain foundations and replaces it with an emphasis on criticism and error correction.

The Open Society

This is the political philosophy of Critical Rationalism, detailed by Karl Popper in The Open Society and Its Enemies. An open society is one in which each individual is largely enabled to make their own personal decisions, as opposed to a tribal or collectivist society. It replaces the justificationist political question, "Who should rule?", with the fallibilist question: "How can we structure our institutions so that we can remove bad rulers and bad policies without violence?". In this view, democracy is not "rule by the people" (an essentialist definition) but is valued as the only known institutional mechanism for error-correction and leadership change without bloodshed.

Fallibilism

This is the philosophical position that all human knowledge—every belief, theory, and observation—is conjectural, incomplete, and potentially mistaken. It holds that there is no conclusive justification and no rational certainty for any belief. Fallibilism is distinct from skepticism. Skepticism argues that because certainty is impossible, knowledge is impossible. Fallibilism agrees that certainty is impossible but denies that this invalidates knowledge. Fallibilism holds that people can and do possess real, objective knowledge, and that people can improve it through a process of error correction.
