Not Until The Empirical Resources Are Exhausted,

Observation Always Involves Theory.

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.

With Increasing Distance, Our Knowledge Fades, And Fades Rapidly. Eventually, We Reach The Dim Boundary-the Utmost Limits Of Our Telescopes. There, We Measure Shadows, And We Search Among Ghostly Errors Of Measurement For Landmarks That Are Scarcely More Substantial. The Search Will Continue. Not Until The Empirical Resources Are Exhausted, Need We Pass On To The Dreamy Realms Of Speculation.

There We Measure Shadows, And We Search Among Ghostly Errors Of Measurement For Landmarks That Are Scarcely More Substantial.

All Nature Is A Vast Symbolism: Every Material Fact Has Sheathed Within It A Spiritual Truth.
