The following is the original source cited in the sentences below: During these leisure times, those old notions about freedom would steal over me again. When in Mr. Gardner's employment, I was kept in such a perpetual whirl of excitement, I could think of nothing, scarcely, but my life; and in thinking of my life, I almost forgot my liberty. I have observed this in my experience of slavery--that whenever my condition was improved, instead of its increasing my contentment, it only increased my desire to be free, and set me to thinking of plans to gain my freedom. I have found that, to make a contented slave, it is necessary to make a thoughtless one. It is necessary to darken his moral and mental vision, and, as far as possible, to annihilate the power of reason. He must be able to detect no inconsistencies in slavery; he must be made to feel that slavery is right; and he can be brought to that only when he ceases to be a man.

Douglass argues that to make a contented slave, it is necessary to make a thoughtless one (58).

To accept his condition, a slave should detect no inconsistencies between what slaveholders say and what they do.

It is necessary to annihilate the power of reason to make slaves feel contented, notes Douglass (58).

Douglass recalls, "When in Mr. Gardner's employment, I was kept in such a perpetual whirl of excitement, I could think of nothing, scarcely, but my life; I almost forgot my liberty." (58).

Douglass points out that the moral and mental vision of a slave must be dulled to prevent discontentment from setting in (58).
