Rationality: A Jamesian Thought

Image result for William James

In a Facebook philosophy group one participant asked the others: "What are your thoughts on being a truly rational person?"

I liked my own answer so much I thought I'd reproduce it here. It is direct from the Jamesian playbook.

Rationality consists of two very different pulls: one toward the general and one toward the particular.

We always get a sense of rationality when we learn that two different-seeming things are in some respect the same. When the orbit of the moon is explained by a law that also covers the fall of an apple, or when electricity and magnetism turn out to be the same force. The rational impulse is toward the general.

On the one hand, we have a natural fear of vagueness and so of generality. We want to know the particular workings of things. "Let's be specific." That too is a rational drive.  The encyclopedia is as rational a phenomenon, even as  much an ideal of rationality, as the concise governing law.                                          

A rational mind in the broadest sense can include any mind that feels either of these pulls. A rational mind in the purest sense in one that feels both of them.

Great Chain of Being

One of the points that Lovejoy makes in the book of that title I mentioned last week is the importance, in the Neo-Platonist conceptions and in the later development of the "chain of being" metaphor, of what he calls the principle of plenitude. This is the underlying notion that everything that can exist must exist, that creation would not be possible at all were it to leave gaps.

The value of this idea for a certain type of theodicy is clear enough.

This caused theological difficulties when these ideas were absorbed into Christianity.  I'll quote a bit of what Lovejoy has to say about those difficulties:

"For that conception, when taken over into Christianity, had to be accommodated to very different principles, drawn from other sources, which forbade its literal interpretation; to carry it through to what seemed to be its necessary implications was to be sure of falling into one theological pitfall or another."

The big pitfalls were: determinism on the on…

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.



We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a majestic wate…
