Live both in the future and the past. Who does not live in the past does not live in the future.
Liberty is the prevention of control by others.
Property is not the sacred right. When a rich man becomes poor it is a misfortune, it is not a moral evil. When a poor man becomes destitute, it is a moral evil, teeming with consequences and injurious to society and morality.
Liberty is the harmony between the will and the law.
Authority that does not exist for Liberty is not authority but force.
There is not a more perilous or immoral habit of mind than the sanctifying of success.
