Aworkshop was held August 26–28, 2015, by the Earth- Life Science Institute (ELSI) Origins Network (EON, see Appendix I) at the Tokyo Institute of Technology. This meeting gathered a diverse group of around 40 scholars researching the origins of life (OoL) from various perspectives with the intent to find common ground, identify key questions and investigations for progress, and guide EON by suggesting a roadmap of activities. Specific challenges that the attendees were encouraged to address included the following: What key (...) questions, ideas, and investigations should the OoL research community address in the near and long term? How can this community better organize itself and prioritize its efforts? What roles can particular subfields play, and what can ELSI and EON do to facilitate research progress? (See also Appendix II.) The present document is a product of that workshop; a white paper that serves as a record of the discussion that took place and a guide and stimulus to the solution of the most urgent and important issues in the study of the OoL. This paper is not intended to be comprehensive or a balanced representation of the opinions of the entire OoL research community. It is intended to present a number of important position statements that contain many aspirational goals and suggestions as to how progress can be made in understanding the OoL. The key role played in the field by current societies and recurring meetings over the past many decades is fully acknowledged, including the International Society for the Study of the Origin of Life (ISSOL) and its official journal Origins of Life and Evolution of Biospheres, as well as the International Society for Artificial Life (ISAL).

This paper deals with Plato’s theoretical views on rhetoric, its value, its conditions, and its genuine ethical-political function. My goal is to show that, even from the theoretical and/or metarhetorical point of view (Gorgias and Phaedrus), Plato would admit the practice of arguing from probabilities (eikós) and opinions, and would accept as a legitimate part of rhetoric –in order to persuade the mob– devices such as appeals to emotion. As it is well known, concrete uses of these devices can be (...) found in the dialogues. I will refer, in this vein, to some passages of Plato’s political writings, esp. Republic and Laws, and to the role of some myths in the dialogues. Nonetheless, I sustain the necessity (and the possibility) of harmonizing this view, with Plato’s strong claim that knowledge of (and commitment to) an objective truth is essential to the true rhétor.
