Darwin's model of evolution . . ., being basically a theory of historical reconstruction, . . . is impossible to verify by experiment or direct observation as is normal in science . . . Moreover, the theory of evolution deals with a series of unique events, the origin of life, the origin of intelligence and so on. Unique events are unrepeatable and cannot be subjected to any sort of experimental investigation.

I argued that it was important not to place too much reliance on any single piece of experimental evidence. It might turn out to be misleading, as the 5.1 Å reflection undoubtedly was. Jim was a little more brash, stating that no good model ever accounted for all the facts, since some data was bound to be misleading if not plain wrong. A theory that did fit all the data would have been "carpentered" to do so and would thus be open to suspicion.

As I admired it [a red pencil and chalk drawing by Degas of a young mother, nursing her child] he showed me a whole series done from the same model and with the same sort of rhythm. He is a draughtsman of the first order; it would be interesting to show all these preparatory studies for a painting to the public, which generally imagines that the impressionists work in a very casual way. I do not think it possible to go further in the rendering of form.

Obviously, the Rraey have some way to predict, with a high degree of accuracy, where our ships are going to skip. How do they do that?”
"I don't think you're supposed to be able to,” I said.
"That's exactly right. But they do anyway. So, quite obviously, our model of how skipping works is wrong. Theory gets thrown out the window when observation proves it isn't so. The question now is what is really going on.
John Scalzi
The critical ontology of ourselves has to be considered not, certainly, as a theory, a doctrine, nor even as a permanent body of knowledge that is accumulating; it has to be conceived as an attitude, an ethos, a philosophical life in which the critique of what we are is at one and the same time the historical analysis of the limits that are imposed on us and an experiment with the possibility of going beyond them.
Michel Foucault
A mechanistic model has the following advantages:
1. It contributes to our scientific understanding of the phenomenon under study.
2. It usually provides a better basis for extrapolation (at least to conditions worthy of further experimental investigation if not through the entire range of all input variables).
3. It tends to be parsimonious (i. e, frugal) in the use of parameters and to provide better estimates of the response.
