Henry David Thoreau on ideas

I have learned, that if one advances confidently in the direction of his dreams, and endeavors to live the life he has imagined, he will meet with a success unexpected in common hours.

To be a philosopher is not merely to have subtle thoughts; but so to love wisdom as to live according to its dictates.

We must walk consciously only part way toward our goal, and then leap in the dark to our success.

Great minds discuss ideas. Average minds discuss events. Small minds discuss people.

Eleanor Roosevelt1884–1962

It is the mark of an educated mind to be able to entertain a thought without accepting it.

One resists the invasion of armies; one does not resist the invasion of ideas.
