What reasoning fallacy is exemplified when one states that the definition of man as a rational animal is absurd based on a baby’s inability to reason?

• A. Vagueness
• B. Ambiguity
• C. Shift of Meaning
• D. No Technique

Answer: (C)

The reasoning fallacy demonstrated in this scenario stems from a misunderstanding of the definition of "man" as a rational animal. The assertion that this definition is absurd because a baby cannot reason involves a shift in meaning. In philosophy, the term "man" when defined as a rational being generally refers to the species as a whole and the inherent potential for rational thought, rather than the current state of every individual at all ages. When one cites a baby's inability to reason as a reason for rejecting the broader definition of humanity, they are incorrectly allowing the specific condition of one subset of humans (infants) to affect the universal definition that applies to all humans in their rational capacity. This is a shift from discussing the nature of humanity at an abstract, categorical level to focusing on the capabilities of a specific developmental stage, which ultimately misrepresents what is being critiqued. Hence, the fallacy of "shift of meaning" aptly identifies the error in reasoning that occurs here.
