There is another question to which an answer must be found, consistent with the principles which have been laid down. In cases of personal conduct supposed to be blamable, but which respect for liberty precludes society from preventing or punishing, because the evil directly resulting falls wholly on the agent; what the agent is free to do, ought other persons to be equally free to counsel or instigate? This question is not free from difficulty. The case of a person who solicits another to do an act, is not strictly a case of self-regarding conduct. To give advice or offer inducements to anyone, is a social act, and may therefore, like actions in general which affect others, be supposed amenable to social control. But a little reflection corrects the first impression, by showing that if the case is not strictly within the definition of individual liberty, yet the reasons on which the principle of individual liberty is grounded, are applicable to it. If people must be allowed, in whatever concerns only themselves, to act as seems best to themselves at their own peril, they must equally be free to consult with one another about what is fit to be so done; to exchange opinions, and give and receive suggestions. Whatever it is permitted to do, it must be permitted to advise to do.
