From Cicero's "De Officiis" (1.71):
Nēmō no one enim for iūstus just esse to be potest is able quī who mortem death timet fears
Nēmō enim iūstus esse potest quī mortem timet. For no one can be just who fears death.
This quote demonstrates how "possum" is used in philosophical contexts to discuss moral possibility. Cicero connects physical ability with moral capability.
-
"potest" takes infinitive "esse" -
Relative clause "quī mortem timet" -
Subject "nēmō" with predicate adjective "iūstus" -
Present tense used for universal truth
