Two quotes: stupidity versus malice.
Here are two related quotes that resurfaced in my life today (well, one did and that always makes me think of the second):
Never attribute to malice that which can be adequately explained by stupidity.
The related quote tracks the famous Clarke’s [Third] Law:
Sufficiently advanced stupidity is indistinguishable from malice.
I love science fiction authors. This stuff never shows up in the literary section.
