3 Carl Sagan Quotes on Ideas

Carl Sagan quotes on ideas

1.

15. Imagination will often carry us to worlds that never were. But without it we go nowhere.

91. The well-meaning contention that all ideas have equal merit seems to me little different from the disastrous contention that no ideas have any merit.
