Malcolm tells Macduff, "Dispute it like a man," (4.3), planning to "make us med'cines of our great revenge / To cure this deadly grief," (4.3) suggesting the appropriate manly response would be to wage war on his enemy. At this point, Malcolm's idea of masculinity seems to be close-minded, in line with his society's. Macduff's reply, "I shall do so; / But I must also feel it as a man; / I cannot but remember such things were / That were most precious to me," marks a moment of learning both for Malcolm and Shakespeare's audience. Macduff implies that repressing his grief would be a denial of his love, and would be unfair to his family's memory. Shakespeare suggests the stone heart of masculinity is unnatural.
