Genius is a nervous disease. [ De Tours ]

A paroxysm of nervous effervescence. [ Douglas Jerrold ]

Woman is the nervous part of humanity; man, the muscular. [ Halle ]

The nervous fluid in man is consumed by the brain; in women, by the heart. [ Stendhal ]

A genius is one who is endowed with an excess of nervous energy and sensibility. [ Arthur Schopenhauer ]

The nervous fluid in man is consumed by the brain; in woman, by the heart: it is there that they are the most sensitive. [ Stendhal ]

There is a magic in the memory of schoolboy friendships; it softens the heart, and even affects the nervous system of those who have no hearts. [ Beaconsfield ]

What we call the heart is a nervous sensation, like shyness, which gradually disappears in society. It is fervent in the nursery, strong in the domestic circle, tumultuous at school. [ Beaconsfield ]

Let your pen fail, begin to trifle with blotting-paper, look at the ceiling, bite your nails, and otherwise dally with your purpose, and you waste your time, scatter your thoughts, and repress the nervous energy necessary for your task. [ G. H. Lewes ]

Be it remembered that man subsists upon the air more than upon his meat and drink: but no one can exist for an hour without a copious supply of air. The atmosphere which some breathe is contaminated and adulterated, and with its vital principles so diminished that it cannot fully decarbonize the blood, nor fully excite the nervous system. [ Thackeray ]
