The outstanding feature, however, is the possibility that the velocity-distance relation may represent the de Sitter effect, and hence that numerical data may be introduced into discussions of the general curvature of space.

Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive to the entire electromagnetic spectrum - we explore the universe around us and call the adventure science.

There we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial.

The universe is unfolding as it should.

Wisdom cannot be directly transmitted, and does not readily accumulate through the ages.

All nature is a vast symbolism: Every material fact has sheathed within it a spiritual truth.
