The unreasonableness of a thing is no argument against its existence, but rather a condition thereof.
The public use of man’s reason must always be free, and it alone can bring about enlightenment among men.[Der öffentliche Gebrauch seiner Vernunft muß jederzeit frei sein, und der allein kann Aufklärung unter Menschen zu Stande bringen.]
The man who listens to Reason is lost: Reason enslaves all whose minds are not strong enough to master her.
That must be, for there is a reason to everything, and nothing happens without a cause, which God sometimes lets students find out.
