Isaac Singer’s protagonist is an aging philosopher who has struggled for thirty years to write a commentary on the 17th century philosophical treatise, Spinoza’s Ethics. Frustrated, sickly and too weak from hunger to get out of bed, a reclusive spinster nurses him back to health. Her kindness leads to marriage and a wedding night in which he miraculously regains his youthful virility and passion for life. The story’s denouement: Spinoza, forgive me. I have become a fool. could thus be taken several ways. Themes: obsession, isolation and loneliness, renewal through passion, the difficulty in reconciling Spinoza’s views with traditional religion.
