'One of the great achievements of the last hundred years has been to deaden the human conscience on that subject [gluttony]...this has largely been effected by concentrating all our efforts on gluttony of Delicacy, not gluttony of Excess...She would be astonished...to learn that her whole life is enslaved to this kind of sensuality, which is quite concealed from her by the fact that the quantities involved are small. But what do quantities matter, provided we can use a human belly and palate to produce querulousness, impatience, uncharitableness, and self-concern?...Because what she wants is smaller and less costly than what has been set before her, she never recognises as gluttony her determination to get what she wants, however troublesome it may be to others. At the moment of indulging her appetite she believes that she is practising temperance.'
