But would that mere physical dirt were all that the lad has to contend with. There is the desire of enjoyment. Moral and intellectual enjoyment he has none, and can have none: but not to enjoy something is to be dead in life; and to the lowest physical pleasures he will betake himself, and all the more fiercely because his opportunities of enjoyment are so limited. It is a hideous subject; I will pass it by very shortly; only asking of you, as I have to ask daily of myself—this solemn question: We, who have so many comforts, so many pleasures of body, soul, and spirit, from the lowest appetite to the highest aspiration, that we can gratify each in turn with due and wholesome moderation, innocently and innocuously—who are we that we should judge the poor untaught and overtempted inhabitant of Temple Street and Lewin’s Mead, if, having but one or two pleasures possible to him, he snatches greedily, even foully, at the little which he has? And this brings me to another, and a most fearful evil of great cities, namely, drunkenness. I am one of those who cannot, on scientific grounds, consider drunkenness as a cause of evil, but as an effect. Of course it is a cause—a cause of endless crime and misery; but I am convinced that to cure, you must inquire, not what it causes, but what causes it? And for that we shall not have to seek far. The main exciting cause of drunkenness is, I believe, firmly, bad air and bad lodging. A man shall spend his days between a foul alley where he breathes sulphuretted hydrogen, a close workshop where he breathes carbonic acid, and a close and foul bedroom where he breathes both. In neither of the three places, meanwhile, has he his fair share of that mysterious chemical agent without which health is impossible, the want of which betrays itself at once in the dull eye, the sallow cheek—namely, light. Believe me, it is no mere poetic metaphor which connects in Scripture, Light with Life. It is the expression of a deep law, one which holds as true in the physical as in the spiritual world; a case in which (as perhaps in all cases) the laws of the visible world are the counterparts of those of the invisible world, and Earth is the symbol of Heaven.
