In practice
During a debate, you might say this quote to encourage others to consider opposing views.
The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it.

Sometimes my biography is interpreted as the upbringing of a French aristocrat. It was very, very different. We were a family of mercantile, immigrant Jews.
Our faith is stronger than death, our philosophy is firmer than flesh, and the spread of the Kingdom of God upon the earth is more sublime and more compelling.
For tyme ylost may nought recovered be.
Forming grammatically correct sentences is for the normal individual the prerequisite for any submission to social laws. No one is supposed to be ignorant of grammaticality; those who are belong in special institutions. The unity of language is fundamentally political.
