A person who thinks or meditates, especially one who engages in deep philosophical thought.
From Latin cogitans, present participle of cogitare meaning 'to think.' The word evolved in medieval philosophy to describe practitioners of contemplation and rational thought.
This word was beloved by medieval scholars who wanted a fancy way to say 'the thinker'—it's the kind of term you'd find in dusty philosophy texts where intellectuals talked about themselves in the third person.
