Ice cycles

In the northern hemisphere, evidence of the ice age lie all about us, but it took someone with curiosity and imagination to see this because so much has changed since then, and because human hearts and minds are not sympathetic to that larger and more dangerous world. In addition to curiosity and imagination, Louis Agassiz also had the intelligence, passion, and persistence to document the effects sufficiently to convince others.

But there are limits. Agassiz resisted Darwin’s theories of evolution all his life.
