In Thomas De Quincey's 1823 essay "On the Knocking at the Gate in Macbeth", he describes the effect of the knocking on him when he was a boy: "it [the knocking] reflected back upon the murderer a peculiar awfulness...". What did he mean by this? Does he admits feeling sympathy for Macbeth?
Here is the paragraph in question:
From my boyish days I had always felt a great perplexity on one point in Macbeth. It was this: the knocking at the gate, which succeeds to the murder of Duncan, produced to my feelings an effect for which I never could account. The effect was, that it reflected back upon the murderer a peculiar awfulness and a depth of solemnity; yet, however obstinately I endeavoured with my understanding to comprehend this, for many years I never could see why it should produce such an effect.
