St. Justin occupies a special place in the social study of French Canada. It was there that Léon Gérin began, in 1886, his pioneer study of the rural communities of the province of Quebec. It was on the basis of the data he collected there that he formulated his analysis of rural French Canada as a close causal cycle in which the dominant factors were the family, the land, and religion. The basis of his argument is the proposition that the people of St. Justin lead a life which “presents itself here as a simple juxtaposition of families which are very nearly all equal; nearly all occupied in agriculture; nearly all self-sufficient; but none of which has a higher ambition than to transmit intact the family property to one of the children, although favouring, within the limits of its resources, the settlement of the other children outside the family home.”
He elaborated this proposition into a complex of interlocking institutions which gave to the inhabitants of St. Justin a definite form of social organization, as well as a definite culture. In fact, he built a model which has remained unequalled in the analysis of French Canada. Presented as a functional entity, St. Justin was made to represent a stage in the historical, as well as the geographical, development of Quebec. According to Gérin, St. Justin had reached a balanced relationship among its various institutions. The family unit was said by him to be stable and well-integrated. The size of the farm was in direct relation to the size of the family, and the work on the land, carried out by the members of the family, was limited to their needs. The total output thus depended on the quantity of labour each family could supply for a given unit of land, and on the natural fertility of the soil. The general expectation of the members of a family was limited to the creation and maintenance of a unit of property large enough to supply their daily needs, maintain the aged, and provide for the settlement of those who would have to leave the household to go elsewhere. Such an aim demanded a high degree of personal sacrifice from all the members of a family, and tended to turn family property into a communal possession. While the stability of the family was obtained in this manner, the stability of the community had been achieved through the creation of a single broad social class.
