<p>This volume explores the three normative sciences that Peirce distinguished (aesthetics ethics and logic) and their relation to phenomenology and metaphysics. The essays approach this topic from a variety of angles ranging from questions concerning the normativity of logic to an application of Peirce&#39;s semiotics to John Coltrane&#39;s &quot;A Love Supreme.&quot;</p><p>A recurrent question throughout is whether a moral theory can be grounded in Peirce&#39;s work despite his rather vehement denial that this can be done. Some essays ask whether a dichotomy exists between theoretical and practical ethics. Other essays show that Peirce&#39;s philosophy embraces meliorism examine the role played by self-control seek to ground communication theory in Peirce&#39;s speculative rhetoric or examine the normative aspect of the notion of truth.</p>
