The right answer is A.Quote:
Our society overestimates the contributions of science to the quest for knowledge. Independent of whether great strides have been made in the ability to predict natural events, knowledge at any deeper level, knowledge of things we cannot experience directly, is as illusory as ever. Such knowledge is illusory because incompatible theories may always be postulated to explain observations. How can we “know” which one is correct? Further observations may narrow the possibilities, but there are always alternatives, at least in principle. Who is to say that today’s theories will fare any better than those which, though once accepted, were replaced by wholly different conceptions of nature? It is the height of gullibility or presumption to invest special credence in the current scientific fashion.
Which one of the following claims is central to the author’s argument?
Breakdown of argument:
Conclusion: Our society overestimates the contributions of science to the quest for knowledge. It is the height of gullibility or presumption to invest special credence in the current scientific fashion.
Premise: Independent of whether great strides have been made in the ability to predict natural events, knowledge at any deeper level, knowledge of things we cannot experience directly, is as illusory as ever. Such knowledge is illusory because incompatible theories may always be postulated to explain observations. How can we “know” which one is correct?
Premise: Further observations may narrow the possibilities, but there are always alternatives, at least in principle. Who is to say that today’s theories will fare any better than those which, though once accepted, were replaced by wholly different conceptions of nature?
The question is basically asking us to identify a premise of the argument above. Scanning through the answer choices, it can clearly be seen that A is the right answer.
Quote:
(A) Alternative explanations are possible for any set of observations about nature.
This is correct as the reason why the author claims that our society overestimates the contributions of science to the quest of knowledge is because there are alternative explanations in the form of theories may be postulated to explain observations.
Quote:
(B) Science has made substantial progress in the ability to predict natural events.
Incorrect and out of scope.
Quote:
(C) Science has developed so many theories that it is impossible to know which ones to believe.
It is not a question of whether there are numerous scientific theories thus making it impossible to know which theory to believe but it is a question of the existence of alternative theories that explain the same scientific observation. C is incorrect.
Quote:
(D) It is important that scientists distinguish between prediction and explanation.
This is not a premise of the argument above. D is incorrect.
Quote:
(E) The judgment of scientists as to which theories to accept is suspect, as they tend to follow the latest scientific fashion.
As per the breakdown of the argument, E is not a premise on which the argument relies. E is incorrect.
