- There is the appearance of Design, without a designer.
“A purpose, an intention, or design strikes everywhere the most careless, the most stupid thinker; and no man can be so hardened in absurd systems, as at all times to reject it… hat the works of Nature bear a great analogy to the productions of art is evident: and according to all the rules of good reasoning, we ought to infer … that their causes have a proportional analogy.” (David Hume)
Since you admit there is an appearance of Design it must be the best available explanation - if it produces scientific evidence. And if Design is the best available explanation the only explanation of Design is an Intelligence because, as you agree, design presupposes intelligence.
Since you cannot distinguish the physical and non-physical aspects of intelligence and have no problem with scientists studying the material component of intelligence it is unreasonable to regard intelligent design as unscientific. Why should one aspect of intelligence be unscientific and the other non-scientific when psychology studies the phenomenon of intelligence as a whole? How could you delineate the two aspects? There is no clear borderline between them.
There are a number of competing hypotheses in cosmology with no clear winner but there are only three hypotheses about the origin of intelligent beings:
- Instant Creation.
- Undesigned evolution.
- Designed evolution - which is the clear winner because it is the only adequate explanation of intelligent, purposeful beings.
There is scientific evidence of Design because the physical laws which enable intelligent beings to exist on this planet are
universal. The immense time scale and vast size of the universe make it highly improbable that intelligent beings do not exist elsewhere in the universe. Even if none exist it does not follow that there is no scientific evidence on this planet. The fact that there are intelligent beings here is sufficient scientific evidence for the existence of an intelligent Being. As David Hume noted, the cause must be proportioned to the effect.
Since there cannot be design without intelligence scientific evidence for Design constitutes scientific evidence for a Intelligent Designer.
One tried and tested way of detecting design is to examine instances of human behaviour to see whether they are rational and purposeful. In the law courts there are definite criteria for determining whether actions are premeditated. SETI is another example.
Design is a far more
adequate explanation of the origin of the universe than speculative cosmologies which ignore the problem of the origin of intelligent beings.
Despite your allegation Design cannot explain everything. For example, it cannot explain the nature and existence of the Designer. It cannot explain the exact proportion of Designed and undesigned events because the scope of the element of chance is difficult to determine but it maintains that the framework of order in the universe and the salient features of evolution are designed. It predicts that the laws of nature will continue to hold good, that robots will never be held responsible for their activity or have the right to exist and that the human mind will never be explained solely by neurological processes.
The Design of living organisms has been implemented physically by the Creation of the universe with its physical laws and physical mechanisms, e.g. the information system contained in the DNA code. It is no accident that the precise values of physical constants and chemical constituents have occurred out of an inestimable number of possibilities.
The
directiveness of evolution is evident in the development of monocellular organisms to intelligent beings. By any standards this is evidence of a clearly defined progression. Monod who believed evolution is due to chance and necessity refers to the “general **upward **course of evolution”. Even mechanistic explanation of the functions of one living cell is now recognized by many biologists as an inadequate approach that must be supplemented by the concept of
goal-directed activity.
