Plato’s thinking on courage, manliness and heroism is both profound and central to his work… his developing critique of both the notions and embodiments of manliness prevalent in his culture (particularly those in Homer), and his attempt to redefine them in accordance with his own ethical, psychological and metaphysical principles.
This passage identifies Plato’s systematic critique and redefinition of manliness as central to his ethics, psychology, and metaphysics, framing the entire inquiry that connects andreia to questions of gender, virtue, and the good.
