Philippa Foot

What It Covers

Philippa Foot (1920-2010) challenged mid-century moral subjectivism by developing virtue ethics grounded in Aristotelian naturalism, arguing that human flourishing requires virtues as objectively as plants need water to thrive.

Key Questions Answered

• •Fact-Value Distinction: Foot dismantled A.J. Ayer's claim that moral judgments merely express subjective approval by analyzing words like "rude" and "dangerous" that inherently blend factual description with evaluative content, showing values cannot be cleanly separated from facts.
• •Trolley Problem Framework: Foot distinguished morally between allowing one to die while saving five versus actively killing one to save five, arguing the critical difference lies in initiating new causal sequences through interference rather than merely redirecting existing threats.
• •Natural Goodness Theory: Humans need virtues (justice, courage, temperance) to flourish based on species-specific life form requirements—social cooperation, child-rearing dependencies, vulnerability in old age—making moral defects analogous to physical defects in other living organisms like weak-rooted oak trees.
• •Virtue as Corrective: Each virtue addresses specific human weaknesses where we naturally fail—temperance counters excessive pleasure-seeking, courage counters cowardice—making virtues objectively necessary dispositions of will rather than arbitrary cultural preferences or subjective choices about how to live.
