As opposed to nominalism, the doctrine that genera and species are real things or entities, existing independently of our conceptions. According to realism the Universal exists ante rem (Plato), or in re (Aristotle).
As opposed to idealism, the doctrine that in sense perception there is an immediate cognition of the external object, and our knowledge of it is not mediate and representative.
Fidelity to nature or to real life; representation without idealization, and making no appeal to the imagination; adherence to the actual fact.
True realism consists in revealing the surprising things which habit keeps covered and prevents us from seeing. Jean Cocteau

Realism is a bad word. In a sense everything is realistic. I see no line between the imaginary and the real. Federico Fellini
It's time to bury the unreal, failed 'realism' of those who have long thought that dictators brought stability. Elliott Abrams
