Paragraph Completion

Step 1: Understanding the context.
The paragraph is discussing the shift in human thought towards combining the external world of science with internal introspection. It emphasizes the integration of humanism and scientific spirit.

Step 2: Analyzing the options.
- (A) Man (humanism) and Nature (Scientific spirit) are distinct entities: This option doesn't align with the paragraph's idea of overcoming boundaries between the two concepts.
- (B) Scientific spirit still stands in opposition to humanism: This contradicts the idea of progress and integration mentioned in the paragraph.
- (C) There is a growing synthesis between humanism and scientific spirit, resulting in a kind of scientific humanism: This option correctly conveys the idea of merging the two ideals, which fits the flow of the paragraph.
- (D) Our five senses and what they can perceive obviously do not exhaust the universe: This doesn't logically continue the paragraph's discussion of humanism and scientific spirit.

Step 3: Conclusion.
The correct answer is (C) because it aligns with the theme of integrating humanism and scientific spirit.
