Rachel Levy, education blogger and essayist, reflects on the reformy love of urgent change and disruption.

When you read the reformy tracts, there is always appeals to act without delay or even pausing to think.

If a man is drowning, you act quickly to throw him a lifeline; you do not act quickly by measuring the depth of the water and agreeing to measure it more frequently.
