# An unrolled scroll supplies no moral destination

Commentary on Orthodoxy by G. K. Chesterton.

On [CH07.P009](https://glosses.org/orthodoxy/pg16769-r1/CH07.P009/#char=254,308): "Evolution is a metaphor from mere automatic unrolling."

The unrolling is a real piece of word history, rather than an image invented for this argument. Latin *evolutio* referred to unrolling a scroll; English also acquired military uses for changes of formation, before the modern biological sense became established. Jeremy Marshall, an editor and researcher for the Oxford English Dictionary, traces these meanings in [his account of the word](https://blog.oup.com/2015/05/word-evolution-etymology/), especially ‘Evolution before Darwin.’

Chesterton selects the older physical image to make a distinction about purpose: movement or unfolding cannot by itself tell us what deserves to exist. His opening concession that the choice of words need not be debated matters. The paragraph is offering a deliberately useful vocabulary for action, rather than proving a moral theory from Latin roots. ‘Reform implies form’ makes the desired standard visible; it does not yet establish which form is right. That unresolved question drives the ensuing argument about a fixed ideal.
