This country, with its institutions, belongs to the people who inhabit it. Whenever they shall grow weary of the existing government, they can exercise their constitutional right of amending it, or exercise their revolutionary right to overthrow it.
To enjoy freedom ... we have of course to control ourselves. We must not squander our powers, helplessly and ignorantly, squirting half the house in order to water a single rose.
Science has gone a long way toward helping man to free himself from the burden of hard labor; yet, science itself is not a liberator. It creates means, not goals. It is up to men to utilize those means to achieve reasonable goals.
A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable.
... how have I used rivers, how have I used wars
to escape writing of the worst thing of all--
not the crimes of other, not even our own death,
but the failure to want our freedom passionately enough
so that blighted elms, sick rivers, massacres would seem
mere emblems of that desecration of ourselves?
