Step 1: Concept
Realism as an orthodox philosophy and its relation to the Platonic theory of forms.
Step 2: Meaning
Realism, in philosophical terms, refers to a set of theories that assert the existence of abstract objects independent of our perception. The Platonic theory of forms suggests that there are perfect, unchanging, and eternal forms or ideas which exist independently of the physical world and serve as the ultimate reality.
Step 3: Analysis
The statement given mentions two aspects:
1. Realism is an orthodox philosophy.
2. It was developed from the Platonic theory of forms.
However, the provided reasoning states that realism denotes two distinct sets of philosophical theories: one concerning the nature of universal concepts and another dealing with knowledge in the world. This reasoning does not align with the development of realism from the Platonic theory of forms as it is traditionally understood. The Platonic theory of forms primarily deals with the existence of abstract, perfect forms rather than the nature of universal concepts or epistemological theories.
Furthermore, the correct answer states that option D is the right choice, indicating that (A) is not correct but (R) is correct. This implies that while realism can be considered an orthodox philosophy and may have roots in Platonic thought, the provided reasoning does not accurately describe its development from the Platonic theory of forms.
Step 4: Conclusion
The statement about realism being developed from the Platonic theory of forms and denoting two distinct sets of philosophical theories is incorrect. Realism primarily concerns itself with the existence of abstract objects independent of perception, which aligns more closely with the Platonic theory of forms rather than the nature of universal concepts or epistemological theories.
Final Answer: (D)
