  Richard Sylvan (born Routley, 1935–1996) was an Australasian philosopher who was instrumental in starting major schools in: logic (especially paraconsistent and relevant logic), metaphysics (especially Meinongian ontology), and ethics (especially environmental ethics). In a large body of writing, Sylvan urged that, from logic to ecology, we are not now thinking well about big problems—but that we can and must do better. “Philosophers fiddle while the world begins to burn,” he wrote (Hyde 2014, vi). In response, he proposed a highly ambitious and radical philosophical project of re-evaluation, from foundations up, that has had ongoing impact in philosophy (Casati, Mortensen &amp; Priest 2018; Eckert (ed.) 2018; Hyde (ed.) 2019, and Weber (ed.) 2019).
