Excerpt from Theory of Observations This assumption, which may be called the law of causality, cannot be proved, but must be believed; in the same way as we believe the fundamental assumptions of religion, with which it is closely and intimately connected. The law of causality forces itself upon our belief. It may be denied in theory, but not in practice. Any person who denies it, will, if he is watchful enough, catch himself constantly asking himself, if no one else, why this has happened, and not that. But in that very question he bears witness to the law of causality. If we are consistently to deny the law of causality, we must repudiate all observation, and particularly all prediction based on past experience, as useless and misleading. If we could imagine for an instant that the same complete combination of causes could have a definite number of different consequences, however small that number might be, and that among these the occurrence of the actual consequence was, in the old sense of the word, accidental, no observation would ever be of any particular value. Scientific observations cannot be reconciled with polytheism. So long as the idea prevailed that the result of a journey depended on whether the power of Njord or that of Skade was the stronger, or that victory or defeat in battle depended on whether Jove had, or had not, listened to Juno's complaints, so long were even scientists obliged to consider it below their dignity to consult observations. But if the law of causality is acknowledged to be an assumption which always holds good, then every observation gives us a revelation which, when correctly appraised and compared with others, teaches us the laws by which God rules the world.

Excerpt from Observations Upon the Natural History of Epidemic Diarrhoea The causative agencies from which springs the plentiful harvest of child mortality in large cities may be conceived as a felted mass of rootlets almost inextricably intertwined. Those of poverty, bad housing, bad feeding, and neglect, may be severally recognized, but the extent of their interrelations with actual respiratory and alimentary disease - those to which the greater part of the mortality is referred - can be traced only with difficulty. It is the object Of this work to aid ln the labour of cutting away the matrix and entangling fibres and to lay bare the hidden ramifications of at least one important causative agency - epidemic diarrhoea. This affection - if we accept provisionally the more novel and generally favoured conception. As to its nature - is revealed as something very like an ordinary infectious disease, and one which permeates all classes, while the excessive mortality it gathers round itself in urban centres must be regarded as something superadded, owing to the vicious circle it forms with those baneful conditions of slum life mentioned above. On the other hand, its peculiarly intimate association with the circum stances of domestic life, from the continual faecal pollution of the interior of the household by infants and others, tends to make it more so than other affections of the kind peculiarly a class disease, and an especial scourge of dirty neighbourhoods. Dirty towns may however be saved from excessive mortality by a high percentage of breast feeding. A notable point in the interesting comparison that can be drawn between diarrhoea and typhoid fever is that, in accordance with their peculiarly opposite age-incidence curves, the marked and habitual depositing of infectious excreta within the household in the former disease may make the question of water-closet versus conservancy pan a matter of far less importance than in the latter.
