Most luxuries, and the so-called comforts of life, are not only indispensable, but positive hindrances to the elevation of mankind. with respect to luxuries and comforts, the wisest have ever lived a more simple and meager life than the poor. the ancient philosophers, chinese, hindu, persian, and greek, were a class than which none had been poorer in outward riches, none so rich inward. we know not much about them. it is remarkable that we know so much of them as we do. the same is true of the more modern reformers and benefactors of their race. none can be an impartial or wise observer of human life but from the vantage ground of what we should call voluntary poverty. henry david thoreau's thinking is: a) inductive b) deductive

B). Deductive.

Explanation:

Deductive thinking is demonstrated as the approach of logical thinking in which the generalized statements or premises are considered and assumed to be true in order to reach a certain yet specific logical conclusion.

In the given excerpt, Thoreau adopts the 'deductive thinking' approach as he uses the general statements 'Most luxuries,...comforts of life, are not only indispensable, but positive hindrances to the elevation of mankind', 'the wisest have ever lived a more simple and meager life' and assume them to true to reach a specific conclusion that 'None can be an impartial or wise observer of human life but from the vantage ground of what we should call voluntary poverty'. Thus, the author reaches a specific conclusion using the general statements. Therefore, he adopts a deductive approach and hence, option B is the correct answer.
