 Positivism is part of a more general ancient quarrel between philosophy and poetry, notably laid out by Plato and later reformulated as a quarrel between the sciences and the humanities.Plato elaborates a critique of poetry from the point of view of philosophy in his dialogues "Phaedrus" 245a, "Symposium" 209a, "Republic" 398a, "Laws" 817 b–d and "Ion".Wilhelm Dilthey (1833–1911) popularized the distinction between Geisteswissenschaft (humanities) and Naturwissenschaften (natural sciences).
