Q:

In the following question, a passage is given which describes a situation. From the given options, mark the correct inference that can be drawn from the passage. If none of the inferences follow, mark option 5, “None of these” as the answer.
The philosophy of pragmatism goes something like this. The mind is such that it deals only with ideas. It is not possible for the mind to relate to anything other than ideas. Therefore, it is not correct to think that the mind actually can ponder reality. All that the mind can ponder is its ideas about reality. (Whether or not that is the way reality actually is, is a metaphysical
issue). Therefore, whether or not something is true is not a matter of how closely it corresponds to the absolute truth, but of how consistent it is with our experience.

A) Our experiences define our concept of reality. B) Reality is a metaphysical issue.
C) Pragmatism and reality are two sides of the same coin. D) Our experiences enable us to determine the truth.
 
Answer & Explanation Answer: A) Our experiences define our concept of reality.

Explanation:

The passage states that reality is not an absolute truth, but a result of our consistent experiences. This makes option a is a correct inference made from the passage. Option 2 is a direct statement already made in the given passage. Option 3 cannot be inferred from the passage as ‘pragmatism’ is considered as a philosophy while ‘reality’ is considered as an amalgamation of our experiences. According to the given passage our experiences enables us to determine what is the reality which may or may not be the truth. This makes option 4 incorrect.
