Logical Multiperspectivism

The view that complex problems require multiple logical perspectives held in tension, because no single logic captures everything. A legal case might need formal logic for statutes, narrative logic for witness testimony, and ethical logic for consequences. Logical Multiperspectivism doesn't seek the one true logic for a problem—it moves between logical frameworks, using each for what it reveals, letting them check and complicate each other. It's logic that has learned that one lens is never enough.

"This ethical dilemma can't be solved with just utilitarian logic. Logical Multiperspectivism says: add deontological logic, care ethics logic, virtue logic. Each gives a different answer; none is final. The truth is in the tension between them, not in picking one. Hold multiple logics or hold wrong answers."

Logical Spectralism

The recognition that every logical system is haunted by what it excludes—the inferences it can't validate, the paradoxes it can't resolve, the assumptions it can't examine. Classical logic is haunted by vagueness. Fuzzy logic is haunted by the sharp boundaries it fuzzifies. Paraconsistent logic is haunted by the consistency it tolerates. Logical Spectralism studies these ghosts—not to exorcise them but to make them visible, to remember that every logic is partial, that every system has a shadow, and that logical humility means knowing what your logic cannot see.

"Your classical logic proves the argument valid. Logical Spectralism asks about its ghosts: the ambiguity in the premises, the context that shifts meaning, the assumptions you didn't state. The logic is sound; the ghosts are real. Your conclusion might be haunted by what logic couldn't handle."

Logical Spectrumism

The view that logical properties exist on spectra rather than in binaries. Truth values can be matters of degree (fuzzy logic). Validity can be partial. Consistency can be approximate. Logical Spectrumism replaces the sharp binaries of classical logic with continuous gradients, recognizing that most real reasoning happens in grey zones where true/false, valid/invalid, consistent/inconsistent are endpoints on spectra, not discrete categories. It's logic for a world that doesn't do boxes.

"You keep asking if the argument is valid or invalid. Logical Spectrumism says: it's 73% valid under these interpretations, 45% under those, with some premises more certain than others. The binary question is the wrong tool. Give me a slider, not a switch, and we can actually evaluate."

Logical Biases

Systematic distortions in reasoning that arise not from breaking logical rules but from the way logical systems themselves are constructed, selected, and applied. Unlike cognitive biases (which are psychological), Logical Biases are built into the logic we use—the assumptions that certain logical forms are universally valid, that classical logic is the only logic, that formal validity guarantees truth. Logical Biases include: preferring deductive over inductive reasoning even when deduction isn't appropriate; treating logical consistency as the highest virtue when life requires contradiction; assuming that what's logically possible is actually possible. Logical Biases are what happen when logic becomes ideology—when the tool becomes the master.

Logical Biases "He keeps demanding that my ethical argument be deductively valid. That's Logical Bias—applying deductive standards to ethics, which isn't deductive. His logic biases him against forms of reasoning that don't fit his logical framework. Logic should serve inquiry, not constrain it. When logic becomes a bias, it stops being logic."

Logical Metametabiases

The most meta level of bias: biases about biases about logic—systematic distortions in how we think about our thinking about logical systems. Logical MetaMetabiases occur when we develop theories about logical biases that are themselves biased, creating infinite regress of reflection. They include: assuming we can fully escape logical bias; treating awareness of bias as immunity to it; using meta-analysis as a way to feel superior rather than to understand; creating hierarchies of bias-awareness that become new biases. Logical MetaMetabiases are what happen when reflexivity becomes its own form of blindness—when knowing about bias becomes a way of not seeing your own.

Logical Metametabiases "He's read all the books on logical biases, so now he thinks he's immune. That's Logical Metametabias—using knowledge of bias as a shield against self-examination. Knowing about bias doesn't eliminate it; it just gives you new ways to be biased about bias. The meta-level isn't escape; it's just another level. Thinking you've transcended bias is the ultimate bias."

Logical Double Standards

A fallacy where someone applies logical standards inconsistently—accusing opponents of fallacies while committing the same ones, demanding evidence they don't provide, requiring certainty they don't practice. The classic form: accusing someone of "jumping to conclusions" while leaping to your own; crying "ad hominem" while attacking character; demanding "evidence" while ignoring counter-evidence. Logical Double Standards reveal that the invocation of logic is often strategic, not principled—logic as weapon, not tool. The double standard is the point: one rule for them, another for us.

"He accused me of hasty generalization based on three examples, then generalized about my entire argument from one comment. That's Logical Double Standards—his generalization is analysis; mine is fallacy. The standard isn't logic; it's convenience. Double standards are what happen when logic becomes a jersey you wear, not a game you play."

Logical Excuse Fallacy

A fallacy where you accuse your opponent of committing logical fallacies specifically to avoid dealing with the content of their arguments. The move uses "that's a fallacy" as a conversation-ender, not a genuine critique. Instead of showing why something is fallacious and what that means, the accuser simply labels and dismisses. The fallacy lies in treating fallacy identification as refutation—as if naming the error does the work of argument. Real fallacy analysis requires showing why the fallacy matters, how it affects the argument, and what remains after it's removed. Logical Excuse Fallacy skips all that and just declares victory.

Logical Excuse Fallacy "He spent the whole debate saying 'that's a straw man,' 'that's ad hominem,' 'that's hasty generalization'—never once engaging what I actually said. That's Logical Excuse Fallacy—using fallacy names as excuses to avoid argument. Real critique engages; labeling just dismisses. The fallacies may have been real; the excuse was the point."
