Séailles was born in Paris. He studied philosophy at the École normale supérieure, then taught philosophy in a number of colleges across France before spending months together with Jules Lachelier, to attend Wilhelm Wundt's lectures about epistemology at Leipzig University.;[1] from this experience abroad he published, besides his logbook, a paper on didactics in Germany.[2] He defended his PhD in literature in Paris in 1884,[3] making his debut as a philosophical writer with his book Essay on genius in art (1883) exposing a theme of his interest in the underlying principles of art. The book on the history of philosophy he wrote with Paul Janet, Les problèmes et les écoles, was published in 1887. Janet was the Sorbonne's Professor of Philosophy and in time Séailles became Janet's successor.
