Book excerpt: This Routledge Revival reissues Oliver Letwin’s philosophical treatise: Ethics, Emotion and the Unity of the Self, first published in 1987, which concerns the applicability of the artistic classifications of romanticism and classicism to philosophical doctrine. Dr Letwin examines three particular theses associated with philosophical romanticism: that there is within us a high self and a low self; that there is a moral self in inevitable conflict with an amoral self; and that there is a rational self disjoined from and in tension with a passionate self. He argues that these notions of philosophical romanticism are, in fact, radically false, and instead takes the view that man can be a unified being of the sort described by philosophical classicists. But man has to work to achieve this status. The intrinsic unity of the human personality is not a guarantee of a coherent life, but a challenge to be met.
