from it,
there are
things that gain, and
those which abhor;
The antifragile is sustained,
The fragile faces horror.

This lyric encodes—for me—the meaning I've taken from Nassim Nicholas Taleb's Antifragile: Things That Gain From Disorder.

Antifragile - by Nassim Nicholas Taleb

Certain aspects or dimensions of our modern world are fragile. When a thing is fragile, it has what Taleb refers to as negative convexity: in other words it is harmed by volatility. The opposite is not robustness—nothing wrong with robustness!—but rather antifragility.

Which systems, industries, professions, roles, activities, etc. benefit from volatility? Taleb invites the read to look around. Published in 2012, more useful than ever.

Taleb is also the author of:

Fooled by Randomness (2001, 2004)
The Black Swan (2007, 2010)
The Bed of Procrustes (2010, 2016)
Skin in the Game (2018)
Incerto's Technical Companion (2020)
