Science rests on reason and experiment, and can meet an opponent with calmness; but a belief is always sensitive.

Summary

This quote suggests that science is grounded in rationality and empirical evidence, allowing it to confront opposing views with composure and objectivity. In contrast, beliefs are portrayed as more delicate and easily disturbed by contradictory perspectives. The implied notion is that beliefs tend to be more subjective and rooted in emotions rather than logical deduction. Therefore, while science can address opposing arguments calmly and resort to evidence-based analysis, beliefs are portrayed as more sensitive and prone to being shaken by opposing viewpoints.
