A neubrutalist forge for structured reasoning
A formal system for constructing valid deductive arguments from premises to conclusions, built on propositional and predicate logic foundations. Handles modus ponens, modus tollens, hypothetical syllogisms, and disjunctive reasoning chains.
Probabilistic graphical model representing conditional dependencies between variables. Propagates evidence through directed acyclic graphs for posterior inference.
Inference to the best explanation system. Generates candidate hypotheses from observations and ranks them by explanatory power, simplicity, and coherence with background knowledge.
Structured argumentation system mapping attacks, supports, and defeats between arguments. Computes grounded, preferred, and stable extensions for conflict resolution.
Kripke semantics-based modal reasoning tool navigating necessity, possibility, and accessibility relations across possible worlds. Supports epistemic, deontic, and temporal modal logics for exploring what must be, what could be, and what ought to be.
Extracts general principles from particular observations. Employs enumerative induction, eliminative methods, and statistical generalization with confidence intervals.
Structural causal model for distinguishing correlation from causation. Implements do-calculus, counterfactual reasoning, and intervention analysis on directed causal graphs.
Analogical reasoning by mapping relational structure between source and target domains. Discovers deep structural parallels while respecting systematicity and one-to-one correspondence constraints.
Higher-order reasoning about reasoning itself. Monitors computational resources, selects appropriate inference strategies, and achieves reflective equilibrium between principles, judgments, and background theories through iterative adjustment cycles.
