Questions about Causality
Short answers, pulled from the story.
What is causality in philosophy?
Causality is an influence by which one event, process, or state contributes to the production of another, where the cause is at least partly responsible for the effect and the effect is at least partly dependent on the cause. Aristotle recognized four types of causal explanation: material, formal, efficient, and final. David Hume later argued that cause and effect cannot be directly perceived, only inferred from the repeated observation of one event following another.
What did David Hume say about causality?
David Hume argued that pure reason alone cannot prove the reality of efficient causality. In Part III, section XV of A Treatise of Human Nature, he listed eight criteria for judging cause-and-effect relationships, requiring that cause and effect be contiguous in space and time, that the cause precede the effect, and that a constant union exist between them. He held that human knowledge of causality derives solely from experience and habit, not from rational insight.
What are the four causes according to Aristotle?
Aristotle identified four explanatory modes: the material cause (what something is made of), the formal cause (its shape or structure), the efficient cause (what set it in motion), and the final cause (its purpose or goal). The word Aristotle used is better translated as "explanation" than as "cause" in the modern sense. Of the four, only the efficient cause corresponds to what most people mean today when they use the word "cause."
What is Judea Pearl's causal calculus?
Judea Pearl's causal calculus, also called do-calculus, is a formal theory that permits researchers to infer interventional probabilities from conditional probabilities in causal Bayesian networks even when some variables are unmeasured. A key practical result is the backdoor criterion, which provides a mathematical definition of confounding and identifies which variables must be adjusted for to isolate a causal effect. The foundational ideas trace back to Sewall Wright's 1921 work on path analysis.
How is causality related to the speed of light in physics?
Causal efficacy cannot propagate faster than light. If it could, the Lorentz transform of special relativity would allow observers to construct reference frames in which an effect precedes its cause, violating causality entirely. Alfred Robb showed that the topological properties of causal antecedence and contiguity can serve as a foundation from which the notions of time and space are derived, making causality metaphysically prior to space-time geometry.
What is an INUS condition in the theory of causality?
An INUS condition, a term introduced by J. L. Mackie, is an insufficient but non-redundant part of a condition that is itself unnecessary but sufficient for an effect to occur. A short circuit in a house fire is the standard example: the short circuit alone would not start the fire, but without it, given the other present conditions, the fire would not have occurred. Mackie's account faces the problem of joint effects from a common cause, which modern regularity theories attempt to overcome.
