Conquest of Abundance: A Tale of Abstraction versus the Richness of Being is the last book by the Austrian philosopher of science Paul Feyerabend, published posthumously by the University of Chicago Press in 1999.

It is edited by Bert Terpstra and includes a foreword from Grazia Borrini-Feyerabend, Feyerabend's 4th and final wife.

The book was uncompleted due to Feyerabend's death in 1994 and was written to fulfill a promise made to Borrini-Feyerabend.

[5] Feyerabend's thesis is not just limited to science, as he uses examples from art history – specifically Brunelleschi's invention of perspective – to substantiate this position.

"Entire communities are displaced, their ways of life destroyed [...] they are unhappy, they protest, even revolt-- but this does not count.

But poets, painters, musicians cherish ambiguous words, puzzling designs, nonsensical movements, all instruments which are needed to dissolve the apparently so rigid and objective nature of scientists, to replace it by useful and changing appearances or artifacts and in this way to give us a feeling for the enormous and largely unfathomable powers that surround us."
