The Warrior Ethos

The Warrior Ethos is a 2011 nonfiction book by American author Steven Pressfield.

It is a unique-style narrative in which Pressfield contemplates the nature of the warrior code and the rules by which a warrior, even a metaphorical one, must follow.

[1][2] He relates several examples from history from the stand of the Spartans at Thermopylae to the defeat of the inner vices as described in the Bhagavad Gita.

[3][4] Pressfield does not define a warrior as a specific martial profession, but broadens it to embrace anyone who faces a conflict they must overcome through trial and effort.

If the code is embraced, it seems to claim any enemy can be conquered, both internal and external.
