We stated in the first chapter that health was secured by obeying the physical laws of our nature; and in the second chapter, that disease was a deviation from a state of health, or an obstruction or diminution of vital energy. The cause of disease must therefore be a transgression or violation of the laws of our nature. This violation may be voluntary on our part, with or without a knowledge of the consequences; it may be produced by circumstances beyond our control, as when we come in contact, inhale or take into our stomachs poisonous substances or gases, or it may be, according to the proverb, "the fathers [or mothers] have eaten sour grapes and the children's teeth are set on edge," or hereditary disease, depending on the transgressions of our forefathers. A fruitful cause of disease is the pernicious fashions of the age. While reason and experience would lead us to obey the laws of our nature, fashion says, Follow me--I will lead you into the paths of pleasure: My laws require no self denial; --eat, drink, sleep, dress, just as the fancy of my directors may dictate, which you will find pleasing to the eye and gratifying to the taste, after you have become accustomed to their use.-- Disease you need not fear, as my friends, the medical faculty, are always ready to administer to you relief; and although they may give you poisons, calculated to produce incurable disease, you should submit patiently, and kiss the rod that inflicts the fatal blow.-- Who would not rather live fashionable, though it produces constant headache, debility, nervous disease, palsy, consumption, rheumatism, gout, etc., and employ fashionable physicians, and take fashionable medicines, though death was the result, than to be called a Grahamite or a Thomsonian ?

To be sure, says fashion, the pleasures I offer you are but for a season, but who would not rather be respected by the rich, and flattered by all, though it lead to sorrow and death, than to live consistently and die in obscurity ?

It is so refined to enjoy a social glass of wine, so beautiful to appear at church with waists of the size of a broom-handle, net-work stockings and slippers in the month of March--so delicious to eat hogs and sheep swimming in grease, rich cakes and pies, bread well buttered and washed down with strong tea and coffee--so gentleman and lady-like to lie in bed till nine o'clock, ride out at eleven, dine at three, and eat a hearty supper at ten--so exquisitely beautiful to appear abroad in curls and ruffles, cane and spectacles, with feet and waists compressed into fashionable shape, with delicate hands and unbrowned face, it is evidence that one does not have to labor for a living. Labor ! says fashion, the bare mention of such a thing would shock the feeble nerves of any of my followers. Labor !! never ! --cheat, lie, steal, rob, anything, rather than submit to work for a living,. Let them do the labor who have not wit enough to get a living without, or so much of that foolish conscientiousness, that they will not cheat when they have an opportunity, to obtain the means of following me.

Thus following such pernicious and foolish fashions is one of the most common causes of disease.

The evils of fashionable life are not confined to the rich, but the laboring portion of community have so mistaken their true interest, as to sacrifice their health and comfort to obtain the means of imitating the rich, and also by the using those means when obtained.

He noble is who noble does. The farmer, mechanic, and manufacturer of that which is useful, are the true nobility. Let them, then, take their proper station in the scale of beings--establish their own customs in accordance with reason and the laws of our nature, so that a proper amount of labor would be made attractive.to all, and all be under the necessity of doing their proportion of all the needful labor--none exempt except from inability, and consequently none over-taxed or over-burdened. All would then have time and opportunity to become acquainted with the physiological laws of their nature, so as to avoid those customs and agents that bring upon them so much disease. The cause of all disease can be clearly traced to the violation of some one or more of the laws of our nature:-1st. By our forefathers; producing in us hereditary taints, such as consumption, scrofula, liver complaints, etc.

2d. Insufficient or too great an amount of exercise. The former producing an inactive state of the organs--the latter producing an exhaustion, in both of which states they do not perform their proper offices. The stomach ceases to secrete the necessary quantity of gastric juice to carry on digestion, the bowels are costive, the morbidic agents generated in the system retained, the wheels of life clogged until exhausted nature gives up the struggle to keep in motion its machinery.

3d. Sudden changes from heat to cold, or cold to heat.

4th. Eating and drinking that which is injurious in itself, or if not injurious in itself, made so by the quantity taken.

5th. Poisons, coming in contact with the surface, taken into the stomach, inhaled into the lungs, or inoculated into the veins; such as the miasma of swamps and lakes, the bite of snakes or any poisonous reptile or animal; the inhalation or inoculation of a poison virus, as the small pox, measles, etc.; taking any substance into the stomach capable of destroying life, in small quantities, although the destruction of life may be prevented by the efforts of nature in expelling it from the system, or protecting herself against its immediate destructive effect, yet rapidly diminishing the vitality of the system, and dragging its victim slowly but surely to the grave.

6th. Mechanical or chemical injuries; such as wounds, cuts, burns, freezes, etc. These causes, acting separately or combined on the human system a length of time, impede the vital functions, obstruct the free operation of the organs, and produce disease.
