What this dot point is asking
OCR Component 01 opens with the ancient philosophical influences that frame the whole paper: Plato and Aristotle. They represent two rival ways of reaching truth. Plato is a rationalist who trusts reason over the senses and locates reality in a realm of perfect Forms; Aristotle is an empiricist who starts from observation and explains the world through four causes and a Prime Mover. The exam rewards understanding each precisely and then evaluating their methods and conclusions against each other.
The answer
Plato and the Theory of Forms
At the top of the hierarchy is the Form of the Good. Just as the sun makes physical things visible and able to grow, the Form of the Good makes the other Forms knowable and gives them their being. Knowing the Good is the goal of philosophy.
The analogy of the cave
Aristotle and the four causes
The final cause is the most important for Aristotle: nature is purposive, and to understand a thing fully is to know what it is for.
Aristotle and the Prime Mover
Rationalism versus empiricism
- Plato distrusts the senses, which show only flux, and trusts reason to reach a higher reality. Knowledge is recollection of the Forms.
- Aristotle trusts observation: form is found within things, not in a separate world, and explanation is by the four causes. His Prime Mover is reached by reasoning from observed motion, not by escaping the physical world.
Examples in context
Try this
Q1. "Aristotle's four causes are a more convincing account of reality than Plato's Forms." Discuss. [40 marks]
- What the marker wants. An AO2 essay setting Plato's rationalism and Forms against Aristotle's empiricism and four causes, weighing whether explanation belongs in a separate realm or within things, and reaching a justified conclusion. The mark scheme awards AO1 out of 25 and AO2 out of 15.
Q2. Assess whether the Prime Mover can be identified with the God of classical theism. [40 marks]
- Cue. The Prime Mover is eternal, immaterial and perfect, which fits classical theism, but it is impersonal, does not create from nothing and does not act in history, which does not. Weigh the overlap against the differences and judge.

A 40-mark Component 01 essay marked on the six-level scheme (AO1 out of 25, AO2 out of 15). Knowledge alone caps in the middle levels; the higher levels reward a sustained argument that judges whether Plato is right to distrust the senses.
Explain the position (AO1). Plato is a rationalist: the senses show only changing, imperfect particulars (a beautiful object), while true knowledge is of the unchanging Forms (Beauty itself), grasped by reason. The cave shows the prisoner reasoning his way out of the world of appearances to the Form of the Good, the source of all other Forms and of knowledge.
Evaluate (AO2). Strengths: the Forms explain how different beautiful things share one quality, and why mathematical truths are certain and timeless. Weaknesses: Aristotle's "third man" regress and the charge that the Forms are an unnecessary duplication of the world; empiricists argue all concepts trace back to sense experience, so reason cannot reach a separate realm.
Judge. A top answer decides whether Plato's distrust of the senses is justified or whether it cuts knowledge off from the only world we can investigate, and defends the verdict. Reaching a clear, reasoned conclusion is what lifts the response to the top level.
OCR H573/01 2021 (style)20 marksTo what extent is Aristotle's Prime Mover a satisfactory explanation of the universe? (The full OCR tariff for this essay is 40 marks; the worked answer below is scaled to a 20-mark exemplar.)Show worked answer →
A levels-of-response essay testing AO1 understanding of the four causes and the Prime Mover and AO2 evaluation of how well they explain reality.
Explain. For Aristotle everything has four causes: material (what it is made of), formal (its structure), efficient (what brings it about) and final (its telos or purpose). The final cause of all motion is the Prime Mover, an eternal, immaterial, perfect being that causes movement not by pushing but by being the object of desire, drawing things towards their purpose as "thought thinking itself".
Evaluate. Strengths: the Prime Mover avoids an infinite regress of movers and grounds the order and purpose we observe empirically. Weaknesses: it is impersonal and uninvolved, unlike the God of classical theism; it explains motion but arguably not why anything exists at all; modern physics questions whether the cosmos needs a final cause.
Judge. A high-level answer weighs whether an unmoved, contemplating mover satisfactorily explains a changing universe, and concludes with reasons.
