He was the forerunner of Lyell and of the uniformitarian school of geologists.
It has often been assumed that Lyell was led by the study of Hutton's works to adopt the uniformitarian' doctrines.
He was ignorant enough to think that the glacial epoch looked like a chasm between him and a uniformitarian world.
The uniformitarian teaching which Lyell deduced from geological observation had gained acceptance.
And here Lamarck, in spite of his uniformitarian principles, is strongly cataclysmic.
This is the uniformitarian view, and is undoubtedly far truer than the catastrophic.
A few, like MacCulloch, undervalued palæontological research, and thus were doubly prejudiced against the uniformitarian views.
