in the realm of ethics, politics, aesthetics it was the authenticity and sincerity of the pursuit of inner goals that mattered; this applied equally to individuals and groups – states, nations, movements. This is most evident in the aesthetics of romanticism, where the notion of eternal models, a Platonic vision of ideal beauty, which the artist seeks to convey, however imperfectly, on canvas or in sound, is replaced by a passionate belief in spiritual freedom, individual creativity. The painter, the poet, the composer do not hold up a mirror to nature, however ideal, but invent; they do not imitate (the doctrine of mimesis), but create not merely the means but the goals that they pursue; these goals represent the self-expression of the artist's own unique, inner vision, to set aside which in response to the demands of some "external" voice – church, state, public opinion, family friends, arbiters of taste – is an act of betrayal of what alone justifies their existence for those who are in any sense creative.[32]
