Alogâmica

Alogâmica is a term that appears in some Portuguese-language discussions to describe reasoning or argumentative processes that do not conform to formal logic. It is not a standard term in major philosophy or logic dictionaries, and its exact sense can vary between authors. The word would be formed from a- (without) + logos (reason, argument) + -mática, yielding a sense of "without logic" or "non-logical."

In typical usage, alogâmica may refer to informal reasoning that relies on intuition, rhetorical effect, or perceptual bias rather than explicit logical validity and soundness. It can also denote artistic, literary, or rhetorical practices that prioritize affect, metaphor, or narrative coherence over strict deduction. Some writers use it to critique arguments perceived as persuasive yet logically flawed, while others study non-logical patterns as part of cognitive or linguistic analysis.

Because it is not standardized, readers should rely on the context in which it appears to determine its precise meaning. It should not be confused with alogia, a medical term for poverty of speech, or with paralogism, a term in logic describing a fallacious form of reasoning that mimics legitimate argument.
