1. natural selection
bait - the survival and reproduction of organisms is a physical process as can be observed
switch - therefore natural selection / differential reproductive success is a physical process
actual - natural selection is actually a comparison of physical processes, it compares reproductionrates, but the comparison is not a physical process. Natural selection solely occurs in the minds of people, there are no comparisons being made in nature between types of organisms.
2. material emotions
bait - alcohol is a chemical, if somebody drinks it their emotional state generally changes
switch - therefore emotions are chemical processes in nature working by cause and effect
actual - when talking about alcohol influencing emotional states, we are looking at alcohol from an anticipation-theory point of view, such as that the alcohol interrupts the rhythm in which we make decisions, it reorganizes the centers of decision in our brain. So our emotions aren't chemical processes in any usual sense of the term working by cause and effect, they are in stead processes of chances being decided in a network of decisioncenters, controlled by immaterial states such as pleasure and pain.
3. evolutionary morality
bait - when talking about goodness in a Darwinian sense, then that is just a technical meaning of goodness as meaning enhancing chances of survival and reproduction, it does not mean moral goodness
switch - there is no such thing as a spiritual goodness or evil, it can't be observed so for as far as science goes it doesn't exist
actual - So to say first Darwinians accept a spiritual goodness so to make natural selection theory distinct from that spiritual goodness and have the theory be descriptive rather then prescriptive. Then they turn around and deny that there is any spiritual realm at all, leaving Darwinian goodness as the only goodness, and natural selection theory as defacto a moral theory about valueing complexity, life, survival and reproduction.
