The final words of Professor Henry's essay titled "The mental Universe" that was published in the journal NATURE in July 2005 are:

"The Universe is immaterial — mental and spiritual. Live, and enjoy."

“All matter originates and exists only by virtue of a force
which brings the particles of an atom into vibration
and holds this most minute solar system of the atom together...
We must assume behind this force the existence of a conscious and
intelligent mind. This mind is the matrix of all matter.”
Max Planck, German theoretical physicist

“The stream of knowledge is heading towards a non-mechanical reality;
the Universe begins to look more like a great thought
than like a great machine."
Sir James Jeans, English physicist, astronomer and mathematician
