He believed that everything arose out of the elemental nature of the universe, which he called the "apeiron" or "unbounded".
As part of his overall attempt to give natural explanations of things that had previously been ascribed to the agency of the gods, such as thunder, the heavens, and the earth, he gave the following account of life.
He thought that the properties of living organisms were due to the mixture of these principles and elements in each part of the body, plus an animating force he called "pneuma", which got translated as "anima" in Latin, the word for "soul".
When asked about his faith, Pasteur would reply: "The more I know, the more does my faith approach that of the Breton peasant.In the "So with animals, some spring from parent animals according to their kind, whilst others grow spontaneously and not from kindred stock; and of these instances of spontaneous generation some come from putrefying earth or vegetable matter, as is the case with a number of insects, while others are spontaneously generated in the inside of animals out of the secretions of their several organs." "As a general rule, then, all testaceans grow by spontaneous generation in mud, differing from one another according to the differences of the material; oysters growing in slime, and cockles and the other testaceans above mentioned on sandy bottoms; and in the hollows of the rocks the ascidian and the barnacle, and common sorts, such as the limpet and the nerites." "Other insects are not derived from living parentage, but are generated spontaneously: some out of dew falling on leaves, ordinarily in spring-time, but not seldom in winter when there has been a stretch of fair weather and southerly winds; others grow in decaying mud or dung; others in timber, green or dry; some in the hair of animals; some in the flesh of animals; some in excrements: and some from excrement after it has been voided, and some from excrement yet within the living animal, like the helminthes or intestinal worms." "Other animalcules besides these are generated, as we have already remarked, some in wool or in articles made of wool, as the ses or clothes-moth.And these animalcules come in greater numbers if the woollen substances are dusty; and they come in especially large numbers if a spider be shut up in the cloth or wool, for the creature drinks up any moisture that may be there, and dries up the woollen substance. A creature is also found in wax long laid by, just as in wood, and it is the smallest of animalcules and is white in colour, and is designated the acari or mite.In books also other animalcules are found, some resembling the grubs found in garments, and some resembling tailless scorpions, but very small.As a general rule we may state that such animalcules are found in practically anything, both in dry things that are becoming moist and in moist things that are drying, provided they contain the conditions of life." "Some writers actually aver that mullet all grow spontaneously.
