Ad Astra per Fatuitatem
“To the stars through stupidity.” I don’t know if I declined fatuitas correctly, I made it dative, but maybe it should be accusative? I was terrible at Latin even while I was studying it. EDIT: A helpful reader has corrected me!
The preposition “per” takes the accusative, so “fatuitatem” would be the appropriate form.
Of course, it’s just through. YES HELLO I GRAMMAR FOR A LIVING
