Option A is incorrect: While the passage draws parallels between science/philosophy and politics/statesmanship, it does not prescribe direct training for every modern statesman in scientific methods and philosophy. That is an extrapolation.

Option B is correct: The passage emphasizes that science without philosophy becomes superficial, and politics without statesmanship becomes bedlam. This implies that governments should not be run solely by empirical/purely technical individuals; they must be tempered with learning, wisdom, and philosophical grounding. Thus, B captures the practical message about governance most rationally.

Option C is incorrect: The passage does not discuss societal education systems or early-age training explicitly.

Option D is incorrect: The passage mentions scientists benefiting from philosophy, but the main focus is on the need for guidance in governance, not prescribing that all scientists must be philosophers.
