Political liberty in a citizen is that tranquillity of spirit which comes from the opinion each one has of his security, and in order for him to have this liberty the government must be such that one citizen cannot fear another citizen.

We ought to be very cautious in the prosecution of magic and heresy. The attempt to put down these two crimes may be extremely perilous to liberty, and may be the origin of a number of petty acts of tyranny if the legislator be not on his guard; for as such an accusation does not bear directly on the overt acts of a citizen, but refers to the idea we entertain of his character.

When the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty; because apprehensions may arise, lest the same monarch or senate should enact tyrannical laws, to execute them in a tyrannical manner.

Liberty itself has appeared intolerable to those nations who have not been accustomed to enjoy it.

Vitam Impendere Vero (I consecrate my life to truth).

The mood and temper of the public in regard to the treatment of crime and criminals is one of the most unfailing tests of the civilisation of any country.

If you run after wit, you will succeed in catching folly.
