Naturalism and Cultural Isms

This is going to build a bit more on my previous post "Naturalism and Human Equality". Naturalism demands that all living entities be ascribed equal value.

This includes bugs and plants. Why should we ascribe greater value to humans? Why not whales, because of their size, or certain trees, because of their long life-spans? If evolution is to be used as a guide, then we must conclude that survivability is the ultimate ascription for value. We could look at survivability of an individual or of an entire species, and we still would not conclude that humans are on top, though.

Useful or Useless Evolutionary Terms?

I want to look at a couple terms that have been added to the evolutionary vocabulary, but are hotly contested:

Microevolution- evolutionary changes that result in differences within a species or genus.

Macroevolution- series of microevolutionary changes that result in a new genus, family, order, etc...

The other day, a naturalist claimed that no such distinction is necessary. The argument is that there is a long string of microevolutionary changes from species to species, from genus to genus, family to family, etc...; macroevolutionary changes are a series of microevolutionary changes that result in a new species, genus, family, etc...; thus macroevolutionary changes are really the same as microevolutionary changes over time. Since they are ultimately the same, there is no need to distinguish between the two terms. This person further claimed that even if they allowed the distinction in terms, the fact that small changes over time is undisputed, means that many changes over time is proven; microevolution is undisputed, therefore a lot of microevolution (macroevolution) is proven.

Default Positions, Atheism, and Fulfillment

Atheists claim that atheism is the default position that people take. Many atheists use this to bolster their philosophy of methodological naturalism in the sciences. But many Christians deny that atheism is the default position. I tend to agree with the atheist, but only to a point. All people are born with a sin nature that denies God, and specifically the Christian God. Technically, Christianity expects that the default worldview of any human being will be anti-Christian, and atheism falls into this category. So, atheism is one of the default positions of man when it comes to a worldview.

However, the atheist is claiming that naturalism is the true worldview. The default position in naturalism, though, is not atheism, as they believe. The default worldview of a person is relative to the culture in which the individual grows up. If the person grows up in an atheist home, and chooses anything other than atheism as their worldview, they have denied their default position in favor of another (be it Hindu, Islam, Christianity, or whatever). However, if a person grows up in a Christian home and remains a Christian, they have stuck with their default position.
