David Hume

David Hume appears as a philosophical reference in an argument about whether temporal succession can be explained by association alone. The passage attributes to him a challenge grounded in experience: an impression, whether strong or weak, contains nothing beyond itself. Its force in the argument is to expose the difficulty of deriving a connection between successive impressions if each is treated as an isolated, self-contained being.

Hume’s Challenge

The discussion situates Hume within associationist theory, which reduces connections among impressions to external bonds, ultimately to before-and-after understood as contiguity. Hume’s challenge is presented as an attempt to establish a law of experience: one may examine any impression at will, but will find only that impression itself. No connection to an antecedent or consequent appears within it, however constant that connection may be.

The Problem of Succession

The passage tests this account by considering two temporal contents, A and B, with B following A. If both exist as self-identical beings-in-themselves, neither contains any internal separation, lack, or trace of what comes next. Their relation of succession therefore cannot arise from either content considered in isolation. The fact that B occurs after A would remain an external relation, unsupported by anything within A or B.

The argument presses the difficulty further: for A genuinely to be prior to B, A must already be incomplete in a way that points toward B as its future. Correspondingly, B must retain A within itself as what it has left behind. Without these relations, the isolated occurrence of B cannot confer posteriority on B or priority on A. Succession would hang, in the passage’s account, in a non-temporal nothingness, unable to connect the two contents.

Role in the Argument

Hume’s challenge supplies the associationist position that the passage scrutinizes, rather than a biographical portrait or an account of his wider philosophy. The author concedes that before-and-after can connect impressions in thought, then argues that temporal unity must be more fundamental than a merely external association: the unity of experience is required for empirical association itself to be conceivable. Hume’s example thus marks the point where isolated impressions fail to explain temporal order, and where the argument turns toward the conditions that make succession intelligible.
