Question

Arrange the following as per the hierarchy of sciences given by Plato: \[ \text{A. Harmonics} \] \[ \text{B. Dialectics} \] \[ \text{C. Arithmetic} \] \[ \text{D. Astronomy} \] \[ \text{E. Geometry} \]

• A. A, B, C, D, E
• B. D, C, A, B, E
• C. C, E, D, A, B
• D. E, D, C, B, A

Hint:

Plato's hierarchy moves from mathematical studies to the highest philosophical method: \[ Arithmetic \rightarrow Geometry \rightarrow Astronomy \rightarrow Harmonics \rightarrow Dialectics \]

Answer 1

The Correct Option is C

Concept:
Plato described a hierarchy of studies that helps the soul move from the visible world toward higher intellectual knowledge. The order moves from mathematical sciences toward dialectics.

Step 1: Start with Arithmetic.
Arithmetic deals with number and is the first important mathematical science. So: \[ C = \text{Arithmetic} \]

Step 2: Next comes Geometry.
Geometry studies spatial relations and forms. So: \[ E = \text{Geometry} \]

Step 3: Next comes Astronomy.
Astronomy studies heavenly motions. So: \[ D = \text{Astronomy} \]

Step 4: Next comes Harmonics.
Harmonics studies mathematical relations in sound. So: \[ A = \text{Harmonics} \]

Step 5: Highest is Dialectics.
Dialectics is the highest method of philosophical knowledge. So: \[ B = \text{Dialectics} \] Thus, the correct order is: \[ C \rightarrow E \rightarrow D \rightarrow A \rightarrow B \] Hence: \[ \boxed{\text{(C) C, E, D, A, B}} \]
