The evils resulting from a violation of Nature’s method of growth by a life of early dissipation are both physical and mental or moral. In some organizations the former, in some the latter, are observable in the most marked degree; but no one can escape either the physical deterioration or the mental degradation which results from the irrational and unhuman exercise of the great endowment of sex. Amongst the physical evils the following may be particularly noted. The loss of self-control, reacting upon the body, produces a morbid irritability (always a sign of weakness) which is a real disease, subjecting the individual to constant excitement and exhaustion from slight causes. The resulting physical evils may be slow in revealing themselves, because they only gradually undermine the constitution. They do not herald themselves in the alarming manner of a fever or a convulsion, but they are not to be less dreaded from their masked approach. The chief forms of physical deterioration are nervous exhaustion, impaired power of resistance to epidemics or other injurious influences, and the development of those germs of disease, or tendencies to some particular form of disease, which exist in the majority of constitutions. The brain and spinal marrow and the lungs are the vital organs most frequently injured by loose life. But whatever be the weak point of the constitution, from inherited or acquired morbid tendencies, that will probably be the point through which disease or death will enter.
