Ransom appears very similar to Lewis himself: a university professor, expert in languages and medieval literature, unmarried (Lewis did not marry until his fifties), wounded in World War I and with no living relatives except for one sibling. Lewis, however, apparently intended for Ransom to be partially patterned after his friend and fellow Oxford professor J. R. R. Tolkien, since Lewis is presented as novelizing Ransom’s reminiscences in the epilogue of Out of the Silent Planet and is a character-narrator in the frame tale for Perelandra.  In That Hideous Strength Ransom, with his royal charisma and casual acceptance of the supernatural, appears more like Charles Williams (or some of the heroes in Williams’s books). 
When the American astronomer James Christy discovered Pluto's largest moon Charon back in 1978, astronomers were quick to calculate the mass of the system. Pluto's mass was hundreds of times smaller than the mass originally estimated for it when it was first discovered in 1930. With Charon's discovery, astronomers suddenly acquired a new understanding that something was fundamentally different about Pluto.
In Western astrology, the Sun represents who we are in the world, the outward projection of our personality, and the mark we wish to make. By contrast, the moon governs our emotions, our primal instincts, and our unconscious mind. It represents a feminine energy, and is often personified as a goddess or mother. In other words, those deep intuitive urges-those passionate feelings we can't quite describe-are embodied in the moon. No wonder so many love poems have been penned under the influence of its rays!
Why hide these accomplishments? It has been difficult to argue for a conspiracy because no theory has offered a sufficiently convincing motive. An idea called "the frontier theory of history" provides two.
