[Extract 1a] Let us then take the case of a man who builds a house for himself on land, and of materials, which nature supplies gratis, and who makes his implements as he goes; the labour of making them being counted as a part of the labour of building the house. He would have to estimate the efforts required for building on any proposed plan; and to allow almost instinctively an amount increasing in geometrical proportion (a sort of compound interest) for the period that would elapse between each effort and the time when the house would be ready for his use. The utility of the house to him when finished would have to compensate him not only for the efforts, but for the waitings. [Extract 1b]
