UGC NET Paper 1: Unit 6 (Logical Reasoning)

Analogical Arguments

Understanding inductive reasoning based on comparison, structure, and evaluation.

1. Definition & Nature

An analogical argument is a form of inductive reasoning that relies on the comparison of two or more things that are alike in certain respects. It assumes that because two things share some similarities, they are likely to share other similarities as well.

Nature of Arguments (Exam Key)

  • Analogical Arguments are Inductive in nature. Asked in Exam
  • The conclusion can be no more than probable. Asked in Exam

Evaluation Rule

Unlike deductive arguments (Valid/Invalid), analogical arguments are evaluated as Strong or Weak.

Calling them deductive is incorrect. They reason from observed similarities to probable conclusions. Asked in Exam

2. Structure & Exam Formula

A

Object A

Prop X Prop Y Prop Z

Compare Similarities

⬇️ Inference
B

Object B

Prop X Prop Y Likely Z?

🎓 The Exam Formula:

"A" has characteristics of 'X" and 'Y". 'B' has characteristics of 'X" and 'Y". 'A' has the characteristics of 'Z'. Therefore 'B' has the characteristics of 'Z'.

This is Argument from Analogy
