"The importance of this powerful agency, for the prevention of injurious acts, is too obvious to need to be illustrated. If sufficiently at command, it would almost supersede the use of other means...

"To know how to direct the unfavourable sentiments of mankind, it is necessary to know in as complete, that is, in as comprehensive, a way as possible, what it is which gives them birth. Without entering into the metaphysics of the question, it is a sufficient practical answer, for the present purpose, to say that the unfavourable sentiments of man are excited by everything which hurts them."

It is strange that a writer who considers the pain derived from the unfavourable sentiments of others as so acute that, if sufficiently at command, it would supersede the use of the gallows and the tread-mill, should take no notice of this most important restraint when discussing the question of government. We will attempt to deduce a theory of politics in the mathematical form, in which Mr Mill delights, from the premises with which he has himself furnished us.

PROPOSITION I. THEOREM.

No rulers will do anything which may hurt the people.

This is the thesis to be maintained; and the following we humbly offer to Mr Mill, as its syllogistic demonstration.

No rulers will do that which produces pain to themselves.

But the unfavourable sentiments of the people will give pain to them.

Therefore no rulers will do anything which may excite the unfavourable sentiments of the people.

But the unfavourable sentiments of the people are excited by everything which hurts them.
