"...a hard heart is no infallible protection against a soft head"
In his Abolition of Man, C.S. Lewis points out the danger of some educators who seek to do away with all that is emotional and heartfelt in education...
“I think Gaius and Titius may have honestly misunderstood the pressing educational need of the moment. They see the world around them swayed by emotional propaganda—they have learned from tradition that youth is sentimental—and they conclude that the best thing they can do is to fortify the minds of young people against emotion.
My own experience as a teacher tells an opposite tale. For every one pupil who needs to be guarded from a weak excess of sensibility there are three who need to be awakened from the slumber of cold vulgarity. The task of the modern educator is not to cut down jungles but to irrigate deserts.
The right defence against false sentiments is to inculcate just sentiments. By starving the sensibility of our pupils we only make them easier prey to the propagandist when he comes. For famished nature will be avenged and a hard heart is no infallible protection against a soft head.”–C. S. Lewis, The Abolition of Man
