Reconstructing Knowledge and Belief: Empirical Foundations in Ayer and Ryle

This paper develops a species–genus account of knowledge and belief through a reconstruction of A.J. Ayer’s epistemology, with particular attention to its contrast with Gilbert Ryle’s generic distinction. It argues that basic statements, or basic beliefs, occupy a foundational role in Ayer’s account and possess a distinctive Ayerian epistemic warrant for empirical certainty grounded in observation. These statements are pre-dispositional and may be expressed categorically, independently of causal or hypothetical conditions. By integrating knowing-how with knowing-that, the paper clarifies the role of meaning rules in guiding the correct use of basic statements. It further shows how sense-data can be accommodated within this framework, preserving their epistemic function while avoiding the difficulties raised by Ryle’s critique.
