When they come downstairs from their Ivory Towers, idealists are very apt to walk straight into the gutter.
The idealists will always be in society, and we will survive.
Idealists foolish enough to throw caution to the winds have advanced mankind and have enriched the world.
We are all idealists in that we are ever discontented with the present state of the Ego and the World.
The idealists dream and the dream is told, and the practical men listen and ponder and bring back the truth and apply it to human life, and progress and growth and higher human ideals come into being and so the world moves ever on.
