William O. Douglas,
Dennis v. United States — Dissenting Opinion
“ There comes a time when even speech loses its constitutional immunity. Speech innocuous one year may at another time fan such destructive flames that it must be halted in the interests of the safety of the Republic. That is the meaning of the clear and present danger test. When conditions are so critical that there will be no time to avoid the evil that the speech threatens, it is time to call a halt. Otherwise, free speech which is the strength of the Nation will be the cause of its destruction. ”
