Wherefore the heart and the diaphragm are particularly sensitive, they have nothing to do, however, with the operations of the understanding, but of all these the brain is the cause.
HippocratesWine is an appropriate article for mankind, both for the healthy body and for the ailing man.
HippocratesMen ought to know that from nothing else but the brain come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations. And by this, in an especial manner, we acquire wisdom and knowledge, and see and hear and know what are foul and what are fair, what are bad and what are good, what are sweet and what are unsavoryโฆ. And by the same organ we become mad and delirious, and fears and terrors assail usโฆ.All these things we endure from the brain when it is not healthyโฆ.In these ways I am of the opinion that the brain exercises the greatest power in the man.
