    $\begingroup$ Is "mathematical thought" something different from "mathematics"? $\endgroup$ – Alexandre Eremenko Apr 18 '19 at 10:49
  • $\begingroup$ Welcome to the site. Are you referring to mathematical history (as in this classic) or are you referring to something more specific to the history of logic? $\endgroup$ – Easymode44 Apr 18 '19 at 12:47
  • $\begingroup$ This question is too broad for this site. Type "history of mathematical thought" into Google's search box, select Books, and read the reviews. "Good" depends on what you are looking for. $\endgroup$ – Conifold Apr 18 '19 at 17:56
