Which statement characterizes the rigor associated with Isaac Newton?

• A. Expected detailed arguments with theorems
• B. Methods employed for theorems were less rigorous
• C. Self-evident truths
• D. Firm axiomatic basis

Answer: (B)

The idea here is about how rigor was handled in Newton’s work. Newton often proved results using geometric reasoning and physical intuition rather than a formal, step-by-step, limit-based justification. His calculus, expressed with fluxions and infinitesimals, relied on ideas that weren’t made fully rigorous by later standards. So, while his results were powerful and correct, the precision of his justifications differed from the fully formal, axiomatic style that later mathematicians developed. This is why the description that best fits Newton is that the methods used for his theorems were less rigorous.
