What one man can invent another can discover.

Most new discoveries are suddenly-seen things that were always there.

True originality consists not in a new manner but in a new vision.

When they shout “Long live progress,” always ask, “Progress of what?”

Every man takes the limits of his own field of vision for the limits of the world.

One doesn’t discover new lands without consenting to lose sight of the shore for a very long time.

What one man can invent another can discover.

A man of genius makes no mistakes. His errors are volitional and are the portals of discovery.

There are truths that prove their discoverers witless.

Nature has planted in our minds an insatiable desire to seek the truth.
