From the beginnings of commercial capitalism to modern disputes over evolution, nature has lengthy been a part of the general public debate over the social strong. As such, many ordinary scientists all through American background have understood their paintings as a cultural task contributing to social balance and their box as a robust device for reinforcing the standard of yank lifestyles.

Kennedy INVENTING THE ICE AGE 41 Chapter 4 Inventing the Ice Age: the Rôle of Louis Agassiz ‘Every river appears to consist of a main trunk, fed from a variety of branches, each running in a valley proportioned to its size, and all of them together forming a system of valleys communicating with one another, and having such a nice adjustment of their declivities, that none of them joins the principal valley, either on too high or too low a level; a circumstance which would be inﬁnitely improbable if each of these valleys were not the work of the stream that ﬂows in it’ (John Playfair, 1802, p.
He was, in many senses, overcautious: the North American term ‘pussyfooter’ comes to (my) mind, especially in his dealings with land ice, the work of rain and rivers (and evolution). Whether this was the manifestation of the legal mind; a wish to maintain decorous views which would fail to shock Victorian society; or merely an unduly timorous character, I am unable to judge. It is also the case that The Principles went through 11 editions during his lifetime and it has so far been more than any scholar can face to develop a true variorum edition.

Just to further confuse the issue, he adds: ‘In thus accomplishing a certain end, we are not to limit nature with the uniformity of an equable progression, although it be necessary in our computations to proceed upon equalities’ (p. 197). By this last, I think, he just means that we have to try to work out average rates, although reality will exhibit ﬂuctuations from those averages. I stated earlier (p. 17) that Hutton’s 1795 treatise did little to clarify the thrust of his thinking. His friend and apologist, John Playfair (1747–1819), Professor of Natural Philosophy at Edinburgh, attempted a wholesale rescue operation with his Illustrations of the Huttonian Theory of the Earth (1802).
