We are glad to present the nineteenth volume of this journal. Its unitary thematic focus concerns a fruitful discussion of a variety of approaches in Ancient Epistemology. This volume of Logical Analysis and History of Philosophy presents in total eleven articles on the theme of Ancient Epistemology, ranging from the presocratic philosopher Xenophanes to Plotinus and Sextus Empiricus, both by established colleagues and by younger scholars at the beginning of their career. Many interpretations are new or feature new ideas or new applications of ideas. We are confident that they will stimulate the readers to develop their understanding of ancient epistemology in response to them. The Authors: Matthew Duncombe, Alexander P. D. Mourelatos, Patricia Curd, Lucas Angioni, Ada Bronowski, Lee Franklin, Audrey Anton, David Bronstein, Anna Tigani, Andrew Payne, Eleni Perdikouri, Petter Sandstad, Jared Smith and Ádám Tamás Tuboly.
