Only once, and a tome like that deserves re-reading.

Is this reference to the blind alley of the shopping list, or is it that part set in Rue Reclus?

Most of the time, what I get paid for as a geologist, is not to find a Truth, but just to document what is there. And what might be there. The beginning of science is observation, then synthesis, then thesis. I get paid for observation, my clients usually don't care about synthesis, and thesis is reserved for publications.

I was privileged to have as teachers many of the old guard geologists, the ones who went through the Plate Tectonic Revolution. For the most part, the Geosynclinal model worked for them, based upon the evidence at hand. All of them, while being a bit embarrassed at holding to such a theory, eagerly embraced Plate Tectonics as a better theory, once the evidence was provided, thanks toMarie Tharp, who was just doing her job, and, not, in my opinion, trying to find a Universal Truth.

Often, Truth is found by not looking for it. But you have to be looking.

Does that make any sense?
