1. IDEA 1 OF 6

   The harm principle

   The only justification for limiting a person's freedom is to prevent harm to others.

   Their own good is not enough.

2. IDEA 2 OF 6

   Let opinions collide

   Silencing an opinion is wrong even if it's false.

   If it's true, we lose truth; if false, we lose the clearer understanding that comes from defeating it.

3. IDEA 3 OF 6

   Tyranny of the majority

   Social pressure and public opinion can be as oppressive as unjust laws.

4. IDEA 4 OF 6

   Individuality is essential

   Developing your own character and tastes is central to wellbeing and progress.

5. IDEA 5 OF 6

   Experiments in living

   Society learns when people are free to try different ways of life.

6. IDEA 6 OF 6

   Limit the state

   Government shouldn't decide what is good for individuals in matters that only affect themselves.
