Ellen Key said this quote

Whereas nationalism still seeks power, honour, and glory through means that endanger other countries, patriotism knows that a country's strength and honour can only be permanently safeguarded through concourse with other countries. And whereas nationalism scoffs at the idea of international laws and regulations, patriotism seeks to create such.

~ Ellen Key

It is not a dream that someday, nations will be able to settle their difficulties without war, just as individuals now settle their personal feuds without resorting to arguments of physical strength or sharp steel. For, then, humanity will have created international jurisdiction and a power to enforce its laws.

~ Ellen Key

The storm and stress period of women and the new social and psychological formations thereby entailed must indeed extend far into the twentieth century. This period of conflict will cease only when woman within and out of marriage shall have received legal equality with man.
