I don't think that is what carolinajazz meant by "hogwash".
Life has passed down to us through a process that is brutish, unforgiving, and willing to engage in wholesale slaughter. I don't look to the process of evolution as a guide to proper morality, and the few people who seem to do that are hideous people. Going all the way back to Darwin himself, most biologists wants humans to do better than evolution in the treatment of individuals.
I don't believe in evolution any more than I believe the sun will rise tomorrow. I accept tomorrows sunrise as the inevitable result of the facts regarding the earths rotation, and evolution as the inevitable result of the facts of biology.
As for whether the knowledge of past eras was superior morally, it's just as wrong to say they had better morality as to say they had worse morality.
well, I do think that's his general view, but I will concede the point that he is a biblical literalist. . . . if that's the right term. . . .that he considers the biblical account sacred and maybe even "infallible", and that his arguments run to the point that somehow it can still be defended technically as precise truth which a "true" science could or would validate. I differ from him as I don't think it's prudent to hold God responsible for human ideals to that extent.
I think of Science as a discipline or process for evaluating the world within our "reach" so to speak, considering our various tools as extensions of our "reach". I entertain notions about some limits on its usefulness or meaning, particularly when it is used to invoke sweeping conclusions about the past, the future, or things well outside our experience and knowledge. Extrapolations as well as interpolations sometimes fail, but it is often tempting for us to push the limits and sometimes, especially if it satisfies our demands for "validation" of some sort. That is where it can be called hogwash.
