Logical Puritanism

A culture of purity centered on logical correctness—treating any failure of formal reasoning as not just mistaken but morally suspect, any deviation from logical orthodoxy as corruption. Logical puritanism demands that all arguments be formally valid, all inferences be deductively sound, all reasoning be explicit and complete—standards that no actual human reasoning ever meets. It then uses the inevitable failures as grounds for condemnation, treating the gap between real human cognition and ideal logic as evidence of vice rather than just the human condition. Logical puritanism is what makes online debate so miserable: every rhetorical shortcut is a sin, every informal inference is a crime, and the goal is not understanding but exposure of error.

Example: "He couldn't engage with her argument—he was too busy cataloging every informal fallacy, treating each as a moral failing rather than just how humans talk. Logical Puritanism: making logic a weapon instead of a tool."

Logical Orthodoxy

The established, institutionalized set of beliefs about logic that dominate Western reasoning—the often-unexamined assumptions about what counts as logical, which logical systems are valid, and how logic should be applied. Logical orthodoxy includes specific commitments: that classical logic (with its laws of non-contradiction, excluded middle, and deduction) is the correct logic, that formal logic is superior to informal reasoning, that logical validity is the standard for argument, that contradictions are always errors, that logic is universal and culture-independent. Like all orthodoxies, it provides a framework for evaluating reasoning, but it functions as ideology when it becomes dogmatic—making a particular logical system seem like the only logical system, obscuring how logic varies across cultures and contexts (Buddhist logic, indigenous logic, paraconsistent logic), and delegitimizing alternative reasoning practices. Logical orthodoxy determines what arguments are considered "valid," what reasoning is "sound," and who counts as "logical" versus "illogical."

Example: "He dismissed Buddhist logic as 'just irrational' because it tolerated contradictions—not because he'd examined different logical systems, but because logical orthodoxy had made classical logic feel like Logic itself. The orthodoxy's power is making one system of reasoning feel like the only way to reason."

Logical Projection

A cognitive bias where one projects one's own logical framework onto others—assuming that everyone reasons by the same rules, that what seems logical to one must seem logical to all, and that disagreement can only indicate failure of logic rather than different logical frameworks. Logical projection operates when someone says "that doesn't follow" without considering that their interlocutor might be using different inference rules; when they dismiss non-Western reasoning as "illogical" rather than differently logical; when they cannot recognize that logic itself varies across cultures and contexts. The projection lies in mistaking one's own logic for Logic itself—assuming that the rules one learned are the rules of thought, not just one set among many. It closes off understanding of alternative reasoning systems, treating difference as deficiency.

Example: "He couldn't understand Buddhist logic that tolerated paradox—he just called it irrational. Logical projection: assuming his logic was the only logic."

Logical Contextualism

A philosophical framework holding that logic is context-dependent—that what counts as a valid inference, what logical systems are appropriate, and what standards of reasoning apply vary with the context of inquiry. Logical contextualism challenges the view of logic as a single, universal, timeless system. Classical logic may be appropriate for mathematics; intuitionistic logic for constructive reasoning; paraconsistent logic for handling contradictions; modal logic for necessity and possibility. Contextualism doesn't deny that logic discovers necessary truths, but insists that logical systems are tools whose appropriateness depends on the context of use. It demands that logicians and reasoners attend to the purposes and domains for which a logic is deployed.

Example: "His logical contextualism meant he didn't insist that classical logic was the only correct logic. In dealing with inconsistent databases, he used paraconsistent logic—not because classical logic was wrong, but because context called for a different tool."

Logical Multicontextualism

A philosophical framework holding that logic operates within multiple, irreducible contexts—mathematical, computational, linguistic, philosophical, practical—that interact to shape what logical systems are developed and how they are used. A logical system emerges from the context of mathematical tradition, the context of computing technology, the context of philosophical debate, the context of practical reasoning problems. Multicontextualism insists that understanding logic requires attending to this contextual multiplicity and recognizing that no single context exhausts the meaning or purpose of a logical system. It demands that logicians be aware of the multiple contexts that shape their work and that they resist the temptation to treat their own context as universal.

Example: "Her logical multicontextualism meant she studied the development of modal logic not just through philosophy, but also through the context of early computer science, the context of linguistic semantics, and the context of metaphysical debates—all of which shaped what modal logic became."

Logical Perspectivism

A philosophical framework holding that logic is always from a perspective—that what a logical system reveals depends on the theoretical commitments, metaphysical assumptions, and practical purposes from which it is developed. Logical perspectivism rejects the idea that there is one true logic that captures the structure of reasoning itself. Different logical systems (classical, intuitionistic, linear, modal, paraconsistent) offer different perspectives on reasoning, each illuminating aspects the others leave in shadow. Perspectivism doesn't make logic subjective; it recognizes that logical validity is always validity-from-a-perspective and that the richness of reasoning exceeds any single system. It demands that logicians be explicit about the perspective from which they work.

Example: "His logical perspectivism meant he could work in both classical and intuitionistic logic—not because he was inconsistent, but because each was a perspective suited to different problems: classical for mathematics, intuitionistic for constructive proof."

Logical Multiperspectivism

A philosophical framework holding that reasoning and its formal study require multiple, irreducible logical perspectives—that no single logical system captures the full complexity of inference, and that different systems are not merely competing for the one correct account but are complementary tools for different domains. Logical multiperspectivism rejects the idea of a final, unified logic that would replace all others. Instead, it insists that classical logic, intuitionistic logic, paraconsistent logic, modal logic, and others each reveal genuine aspects of reasoning and are legitimate for their contexts. This framework demands that logicians cultivate pluralism, recognizing that the richness of their subject exceeds any single formalization and that genuine understanding requires moving between perspectives.

Example: "Her logical multiperspectivism meant she taught students not just classical logic, but also intuitionistic, modal, and paraconsistent—not because they'd use all, but because each perspective on reasoning deepened their understanding of what logic could be."
