From Jim Starlin’s 1975 on Warlock.
There’s an essay in Douglas Wolk’s Reading Comics: How Graphic Novels Work And What They Mean called ‘The Dark Mirrors of Jim Starlin’s Warlock' that provides a fantastic analysis of this very unique comics collection. In Wolk's words:
‘The Warlock serial that Jim Starlin wrote and drew between 1974 and 1977 is a crazily dense, heady, philosophy-minded space opera that includes some of the oddest and most dazzling mainstream comic books of their era.’
Wolk on the primary function of Warlock:
‘Mostly, though, Starlin used Warlock as a vehicle for playing with various kinds of dichotomies and dialectics. There are a lot of neatly two-sided conflicts going on in the series—life versus death, order versus chaos, free will versus predestination, and so on—and the characters are only too happy to discuss their respective ideologies, even in the middle of a fight.’
In the particular panel I’ve posted, Thanos spouts a bit of existential Manichaeism at the evil, futuristic version of Warlock: the purple afro’d Magus.
