Defense of the Senses

I've retrieved, from our bookshelves, 2 books: David Kelley's The Evidence of the Senses: A Realist Theory of Perception and Quee Nelson's The Slightest Philosophy. I'm thinking of doing a detailed comparison.

For one thing, is Kelley's "reductive focus" really the same as Nelson's "inviddying of scene-images"? Maybe I need a translation table!  (Update: In both cases the idea refers to the kind of seeing we do when we see that a circular coin "looks elliptical" at an angle.)

Nelson's book is funnier, and easier to read for most people. Kelley's book is addressed to those trained in contemporary philosophy, and is more academic in style.

Both authors are out to rescue the idea that our senses are really in touch with reality. Of course, most people do think this, but many philosophers have thought otherwise!

Quee Nelson has a lot of examples of this skeptical philosophical tradition in her book's appendix. I like this one:
A. J. Ayer: “From our resources of sense-data, we ‘construct’ the world of material things.”
I often get tired constructing the world of matter.
Ideas are so light. You can toss them around with mere chatter.

Material things have such weight.  They're so hard to build with.
But nice fluffy sense-data - that is something I'm skilled with.

You Didn't Need That Laptop, Did You?

The Chicago Tribune reports on the trouble people have taking their laptops out of their cases for TSA searches:
More than 12,000 laptops are lost each week at U.S. airports, according to a study conducted for Dell by the Ponemon Institute, a research think tank. Only one-third of laptops lost and found in airports are reclaimed, the study said.
Wait. So if 12,000 are lost and one-third are returned that's 8,000 lost permanently each week.

That's 416,000 laptops down the drain per year?

No wonder people are nervous
about the TSA's service.
