A Useful Tool Became a Cage. Uniformitarianism Could Not Account for What Was Actually Happening.

Uniformitarianism is not a bad framework. Randall Carlson is precise about that. As a tool for understanding how rivers erode their banks, how surf reshapes coastlines, how earthquakes alter topography - it is powerful and genuinely useful. The principle that the present is the key to the past has produced real and valuable geological knowledge across two centuries of application.

The problem emerged when the tool became a constraint. By the early to mid 20th century, invoking forces or magnitudes beyond what can be observed operating in the present had been declared unscientific. Not simply unconventional. Unscientific. The rates and scales of change visible today became the only rates and scales that geology was permitted to invoke when reconstructing the past. And that constraint - that institutional commitment to gradualism as the only legitimate explanatory framework - became the shortcoming that Randall has spent decades documenting. Because the past did not always operate at the rates observable today. Some of it operated at magnitudes so far beyond the modern baseline that no uniformitarian model can account for what the geological record is actually showing - and the refusal to acknowledge that gap has shaped and limited the entire field.
