It's about math as a human construction. Very comforting to see ones inner metaphores and mental models of math "legitimised" and exposed in a scientific framework. One could hope for a companion: Where Software Engineering Comes From.
Another book on the topic of history of mathematics is "Journey Through Mathematics" by Enrique Gonzalez-Velasco. From its back cover:
"This book offers an accessible and in-depth look at some of the most important episodes of two thousand years of mathematical history. Beginning with trigonometry and moving on through logarithms, complex numbers, infinite series, and calculus, this book profiles some of the lesser known but crucial contributors to modern day mathematics."
