Power itself is servile when it depends upon public opinion; for you are dependent on the prejudices of others when you rule them by means of those prejudices. To lead them as you will, they must be led as they will.

Context

“Do not kick against the stern law of necessity, nor waste in vain resistance the strength bestowed on you by heaven, not to prolong or extend your existence, but to preserve it so far and so long as heaven pleases. Your freedom and your power extend as far and no further than your natural strength; anything more is but slavery, deceit, and trickery. Power itself is servile when it depends upon public opinion; for you are dependent on the prejudices of others when you rule them by means of those prejudices. To lead them as you will, they must be led as they will. They have only to change their way of thinking and you are forced to change your course of action. Those who approach you need only contrive to sway the opinions of those you rule, or of the favourite by whom you are ruled, or those of your own family or theirs.” source
