I ran across this article, part of a series on education by Anthony Esolen. In the course of describing how the modern world wars against our children's souls in ways our ancestors didn't experience, he touches on the topics of play, and why we don't want to be stimulated, and silence.
I think of the Lord speaking to us, in His silence that communicates so much: "Be still, and know that I am God." And that is how I know that these issues are crucial. Some excerpts:
It is noise, rather, that is the absence, both of the significant word and of the fullness of being that silence allows us to hear.
...how petty and dreary a thing it is to be stimulated. The stimulus is the prick or spur you dig into the side of an animal. Imagine the horse, slow moving creature when he is content, with his large sad eyes. If we are to make use of him, we must apply the spur.
It is essentially a pornographic world, where everyone lies naked on a bed of nettles, and every new thing is dead before it is born.
Silence is so great a blessing to us because we cannot use it. All things truly creative, which partake of the spirit of play, send their roots deep down into silence.
