No, no, you're not thinking; you're just being logical.

Attributed to Niels Bohr, this remark draws a sharp line between formal deduction and genuinely creative inquiry. “Being logical” can mean staying within an accepted framework and following its rules to consistent conclusions; “thinking,” in Bohr’s sense, suggests the harder work of questioning premises, imagining alternative models, and tolerating ambiguity when evidence resists tidy explanation. In the context of scientific discovery—especially in early quantum theory—progress often required abandoning classical intuitions and inventing new conceptual tools, not merely applying existing logic. The quote therefore valorizes intellectual flexibility and conceptual imagination over rigid, internally consistent reasoning that may still miss the truth.
