... the philosophy of movie director John Milius.
The director of Dillinger (1973), Conan the Barbarian (1982) and The Wind and The Lion (1975) also wrote the screenplays for these, plus Jeremiah Johnson (1972), The Life and Times of Judge Roy Bean (1972) and bits of Jaws (1975) and Apocalypse Now (1979) .
He was a great believer in taking care of things yourself.
Conan the Barbarian opens with the casting, forging and tempering of Conan's father's sword, and concludes with the father telling a very young Conan ...
"Fire and wind come from the sky,
"from the Gods of the sky.
"But Crom is your God,
"Crom, and he lives in the Earth."
"Once giants lived in the Earth, Conan.
"And in the darkness of chaos...
"they fooled Crom,
"and they took from him the enigma of steel."
"Crom was angered,
"and the Earth shook.
"And fire and wind struck down those giants,
"and they threw their bodies into the waters."
"But in their rage,
"the Gods forgot the secret of steel and left it on the battlefield."
"And we who found it...
"are just men.
"Not Gods. Not giants.
"And the secret of steel has always carried with it a mystery."
"You must learn its riddle, Conan.
"You must learn its discipline."
"For no one,
"no one in this world can you trust;
"not men, not women, not beasts."
(Pointing to his sword):
"THIS you can trust."
The script for Conan is credited to Milius AND to Oliver Stone, but what I've seen of his movies tells me that speech above is pure John Milius, and describes perfectly his philosophy of life,
