which feed the brain causing the flow of blood into it to be stronger or less rapid. If it be true that 'a healthy mind in a healthy body' is the supreme condition of happiness, it is also true that the healthy mind depends more closely than we like to own on the healthy body. These are but a few obvious instances of the manner in which the body acts upon happiness. They do not mean that the will is powerless in the face of bodily conditions, but that in the management of character it has certain very definite predispositions to encounter. In reasonings on life, even more than on other things, a good reasoner will consider not only the force of the opposing arguments, but also the bias to which his own mind is subject. To raise the level of national health is one of the surest ways of raising the level of national happiness, and in estimating the value of different pleasures many which, considered in themselves, might appear to rank low upon the scale, will rank high, if in addition to the immediate and transient enjoyment they procure, they contribute to form a strong and healthy body. No branch of legislation is more really valuable than that which is occupied with the health of the people, whether it takes the form of encouraging the means by which remedies may be discovered and diffused, or of extirpating by combined efforts particular diseases, or of securing that the mass of labour in the community should as far as possible be carried on under sound sanitary conditions. Fashion also can do much, both for good and ill. It exercises over great multitudes an almost absolute empire, regulating their dress, their education, their hours, their amusements, their food, their scale of expenditure; determining the qualities to which they principally aspire, the work in which they may engage, and even the form of beauty which they most cultivate. It is happy for a nation when this mighty influence is employed in encouraging habits of life which are beneficial or at least not gravely prejudicial to health. Nor is any form of individual education more really valuable than that which teaches the main conditions of a healthy life and forms those habits of temperance and self-restraint that are most likely to attain it.
