Friedrich Nietzsche said this quote

It breaks my heart. Better than your words, your eye tells me all your peril.You are not yet free, you still search for freedom. Your search has fatigued you and made you too wakeful.You long for the open heights, your soul thirsts for the stars. But your bad instincts too thirst for freedom. Your fierce dogs long for freedom; they bark for joy in their cellar when your spirit aspires to break open all prisons.To me you are still a prisoner who imagines freedom: ah, such prisoners of the soul become clever, but also deceitful and base.
