Seversky set out the following challenge:
Draw up two lists, the first being all the scientific and technological advances of the last two hundred years, say, that were based on  a naturalistic/materialistic/ physicalist metaphysics,  the second being a list of all such advances based on a teleological metaphysics. A simple comparison should reveal which has been the more prolific and productive approach.
Interesting test. The answer is on list  there would be zero entries. On list  there would be all the scientific and technological advances of the last two hundred years.
You see, Sev, many people spout materialism. No one actually conducts their lives, from moral choices to scientific research, as if it were true. Because if it were true, there would be no point to any moral choice, and there would be no reason to expect that the universe conforms to regularities we call scientific laws. So, even the researchers who spout materialism act as if it were false when they are actually doing research.
This is especially true of biology, including evolutionary biology, where the scientific literature is drenched in teleological language. Why? Because if one wants to describe what is going on, the use of teleological language is unavoidable.
