Necessary Causation in Comte: The Positive Replacement of Causes by Laws

Abstract This article examines Auguste Comte’s response to David Hume’s problem of necessary causation. It is the second piece in a series conceived as a situational overview of how epistemological schools have answered that problem, on which the author will develop his own analysis in a later article. It applies the same framework as the first piece: three levels of Hume’s challenge (conceptual, epistemic, and metaphysical) and a three-dimensional profile (what is justified, at what cost, and what becomes of the original question). The article argues that Comte dissolves the conceptual level by replacing the notion of cause with that of law, understood as an invariable relation of succession and resemblance; leaves the epistemic level open, resting on scientific practice, since the invariability of laws works as an assumption that experience confirms without grounding; and avoids the metaphysical level by prohibition, while affirming an invariable order independent of us. Four objections are reviewed (the verbal character of the renunciation of cause, the status of the invariability of laws, the restriction of hypotheses, and the historical status of positivism itself) along with the replies available in the literature. The assessment describes Comte’s answer as the replacement of the question by a research program, not as a plain success or failure.
