“In scientific thinking are always present elements of poetry. Science and music requires a thought homogeneous.”

“Science fiction is the arena of the not-yet, and every science fiction story has this element of not-yet-ness — usually a bit of technology or a scientific discovery that we don't know about in the real world of the present but that might be a possibility in the future.”

“I think that scientific persons of the future will scoff at scientific persons of the present. They will scoff because scientific persons of the present thought so many important things were superstitious.”

“Laura remarked that science was dependent upon poetry, that all scientific description was metaphoric.”

“Though science makes no use for poetry, poetry is enriched by science. Poetry “takes up” the scientific vision and re-expresses its truths, but always in forms which compel us to look beyond them to the total object which is telling its own story and standing in its own rights. In this the poet and the philosopher are one. Using language as the lever, they lift thought above the levels where words perplex and retard its flight, and leave it, at last, standing face to face with the object which reveals itself.”

“Observation and experience can and must drastically restrict the range of admissible scientific belief, else there would be no science. But they cannot alone determine a particular body of such belief. An apparently arbitrary element, compounded of personal and historical accident, is always a formative ingredient of the beliefs espoused by a given scientific community at a given time”
