" Io mi senti' svegliar dentro a lo core Un spirito amoroso che dormiva.."
( Dante, " La Vita Nuova")
" so the heart is the sun of Microcosm,even as the sun deserves to be called the heart of the world, for it's the heart by whose virtue and is preserved from corruption and coagulation, it is the household divinity which, discharging its function, nourishes, cherishes, quickens the whole body, and is indeed the Foundation of life, the source of all action." ( William Harvey)
" C'est Le Coeur qui sent Dieu, et non la rasone. Voalá ce C'est que la foi. Dieu sensible au coeur,non á la raison." ( Au XVII siécle, Blaise Pascal )
So, in my Opinion The last text speaks about the Catholic idea against the Protestant force ( because of the appearing century, and the Christian connections) But I also can find an " internal truth" behind that curtains.
