We cannot call that a sense of Justice which merely binds a man to a certain number of his fellow-criminals, in order the more effectually to plunder and kill honest men.

Instead of Justice, it is the essential condition of success in Injustice.
If it be said in reply, that these men tacitly assent in their minds to what their practice contradicts, Locke answers, first, that men's actions must be held as the best interpreters of their thoughts; and if many men's practices, and some men's open professions, have been opposed to these principles, we cannot conclude them to be Innate.
Secondly, It is difficult for us to assent to Innate Practical Principles, ending only in contemplation.

Such principles either influence our conduct, or they are nothing.

There is no mistake as to the Innate principles of the desire of happiness, and aversion to misery; these do not stop short in tacit assent, but urge every man's conduct every hour of his life.

If there were anything corresponding to these in the sense of Right and Wrong, we should have no dispute about them.
