I’ll try to summarize the key points here once more.
Information is physical complexity which may occur through natural causes or crafted by intelligent agents. How can one determine when information is generated by an intelligent agent? Meyer focuses his book on the ID claim that when information is complex and specified, it necessarily comes from an intelligent source. Information, he states, can be specified either by being “functional” or by having “meaning.” He shows that DNA information is of the “functional” type.
The question is raised here whether Meyer has adequately demonstrated the claim that both “functional” and “meaning” type of information must come from intelligence. I suggest that only the “meaning” part has that characteristic and not the purely “functional.” The rationale is that “meaning” is the abstract significance applied to a physical configuration, a feat characteristic of intelligence. All the examples Meyer brings forth to demonstrate how information comes from an intelligent source involve “meaning” or a mixture of “meaning” and “function.” Functional configurations can occur in nature that are quite complex and need not have an intelligent source. This leaves open the question of whether DNA information was derived from an intelligent source.
The second claim examined in the lecture deals with the post on historical causal analysis. To be scientific, a claim for having detected a designer for some event, must involve a designer whose existence and means of design must be independently observable. An indeterminate designer does not meet that criterion.
