Not my favourite Lewis, but I may have read it in the wrong frame of mind and without sufficient focus.

It's an odd little book, on the one hand combatting colourless modernism + scientism in education, but on the other appealing to a universal Tao which stands opposed to such modernism / scientism.

I'm not satisfied with how he hand waves over significant differences between various belief systems to build his Tao, nor with how sometimes (in a typical Lewis move) he throws legitimate science under the bus, seeing in it something sinister and unmaking.

The work is also more than usually of its time. Which does NOT mean we cannot learn from it. Far from it! But it does mean we've moved from the principle battle being fought in this book (against state-planned eugenicisms of mind and body, which threatened to abolish humanity), and thus the threat strikes with far less force.
