Explain Aristotle’s critique of Plato’s Idealism. (2019, 20 Marks)
Plato’s idealism has two storeys. The first is a metaphysics in which true reality lies in eternal, separate Forms, of which sensible things are imperfect copies. The second is a politics in which those who know the Form of the Good must rule an ideal city. Aristotle, twenty years in the Academy, attacked both, insisting that while both are dear, piety requires us to honour truth above our friends (Nicomachean Ethics I.6). Hence his label of realist against Plato’s idealist.
The Metaphysical Critique
- Separation. In Metaphysics I.9 he argues that the substance and that of which it is the substance cannot exist apart. Form is immanent: humanity lives in actual human beings, as their structure and function, not in a second world. This is hylomorphism, form joined to matter.
- Duplication and regress. Positing a Form for every class doubles what must be explained. If a man resembles the Form of Man, a further “third man” is needed to explain the resemblance.
- Causal idleness. The Forms contribute nothing to the movement or any change of things. To call them patterns that things share in is to use empty words and poetical metaphors. His four causes (material, formal, efficient, final) locate explanation inside nature.
- Knowledge from experience. Universals are grasped by induction from particulars, not recollected from a prior life. Knowledge begins in observation.
- The Good. Good is spoken of in many categories, so it is not some common element answering to one Idea. A weaver or a doctor gains nothing practical from contemplating the “good itself”.
The Political Critique
- Excessive unity. A city pushed towards oneness becomes a family, and from being a family, an individual. Similars do not constitute a state: a polis is a plurality of unlike parts.
- Community of property. That which is common to the greatest number has the least care bestowed upon it. Common ownership breeds quarrels and kills generosity; his alternative is property in a certain sense common, but, as a general rule, private.
- Community of wives and children. Diluted kinship yields diluted affection: better… to be the real cousin of somebody than to be a son after Plato’s fashion. The family is the first school of virtue.
- Guardians’ happiness. A whole cannot be happy unless its parts are, yet Plato’s guardians forgo it.
- Rule of law over the philosopher-king. Law is reason unaffected by desire, while even the wisest ruler has passions and no successor.
- Experience. Institutions as old as property and the family would have been discarded long ago if bad: we should not disregard the experience of ages. Hence the best practicable constitution, polity, replaces the perfect city.
Limits of the Critique
- Aristotle keeps much idealism. He retains a telos, a best state in Books VII–VIII, natural hierarchy, and politics as the cultivation of virtue.
- Plato has replies. His communism bound only the guardians, and in the Laws he himself turned to law, private property under limits and a mixed constitution.
- “Realist” here means empirical and comparative, not value-free: Aristotle never separates fact from value.
Indian Resonance
Aristotle’s preference for tested experience over deduction echoes in India’s constitution-making. On 4 November 1948 Bhimrao Ramji Ambedkar defended its borrowings: a constitution framed so late in history could hardly be wholly new, and borrowing adapted to Indian needs was no fault.
Conclusion
Aristotle did not reject ideals; he relocated them. The standard of the good moves from a separate heaven into human function, and the best state from philosophy to practice. That relocation founded political science as a comparative, practical discipline.
