Aren't we already doing that when we talk about mental states like beliefs, desires, intentions, emotions and knowledge?

Are you suggesting that mental states don't actually exist?

However, it has come to my attention that Thomas Nagel is an atheist who rejects theism, and yet he is pursing the possibility that teleology may do a better job than materialistic evolutionary naturalism, to explain our world.
Felix wrote: ↑June 4th, 2018, 5:40 amI see no evidence to suggest this may be the case. Just as gravity requires no intentional purpose to cause all celestial bodies in the cosmos to form in the shape of spheres, why would the evolutionary process require any such intention in order for life to emerge? Natural selection explains perfectly how simplicity evolves into complexity without the necessity of a predetermined purpose.Thinking critical: Reason, purpose and intention it seems are simply not a necessary property of existance.Not necessary for existence, but necessary for life and it's evolution.
Thinking critical: "Natural selection explains perfectly how simplicity evolves into complexity without the necessity of a predetermined purpose."I said nothing about "predetermined purposes," only intentional behaviour (conscious or not), which can be seen throughout Nature.

Natural selection does not explain why the simplest life forms should evolve into more complex ones when doing so would greatly decrease their reproductive and adaptive capacity. For example, it is estimated that cyanobacteria have thrived on earth for over 3 billion years. Such simple organisms are far and away the fittest in terms of survival, and so according to the principles of natural selection, the evolutionary process should have ended there - no survival advantage, only disadvantages, could be gained from increased complexity.

Behahaviour, therefore, is no indication as to why the entity exists or how its character was formed. Behaviour is uninformative as regards the primary causes or ultimate destiny of things that currently exist.
Natural selection does not explain why the simplest life forms should evolve into more complex ones when doing so would greatly decrease their reproductive and adaptive capacity.Natural selection is one of the processes driving evolution. Another factor is change in the environment, whereby an established life-form that was well adapted to the old conditions finds itself less capable in the new ones; in this case, a variant with a minute degree greater complexity might gain the advantage. Another factor is overcrowding when conditions have favoured a particular adaptation and competition for resources grows fierce, in which case, the ability to feed on an unaccustomed substance would an advantage to the life form with a more complex metabolism. In other overpoluplated situations, the advantage might go to the variant that is able to migrate to another location. And so on.
Natural selection is one of the processes driving evolution.I am aware of the arguments for natural selection, and as I suggested, it doesn't seem reasonable to me that a mindless, random process could lead to such an increase in the complexity of life forms - variations in simple life forms, yes, but the sheer creative and progressive fecundity of Nature suggests to me that it cannot be a totally mindless and aimless process, especially since Natural Selection has no answer as to why simple life forms should even arise in the first place.
Felix wrote: ↑June 7th, 2018, 2:10 pmRichard Dawkins in my opinion explains the history of simple life forms evolving to complexity more eloquently than anyone else I have read. He uses the analogy of the journey up mount improbable to explain how very slight genetic variations and mutations can gradually improve an animals ability to survive. For example: shorter legs improve acceleration and longer legs improve top end speed, changes to an eye can increase focus, distance or ability to see in the day or night better. These multiple gradual changes increase genetic information which equates to increased complexity; each gradual improvement is a step up mount improbable.....along this journey there maybe be side steps and steps down as species become extinct and genes lost with them. After 3 odd billion years or so it makes sense and is even more probable than not,that eventually more and more complex life forms, such as ourselves should emerge.Natural selection is one of the processes driving evolution.I am aware of the arguments for natural selection, and as I suggested, it doesn't seem reasonable to me that a mindless, random process could lead to such an increase in the complexity of life forms - variations in simple life forms, yes, but the sheer creative and progressive fecundity of Nature suggests to me that it cannot be a totally mindless and aimless process, especially since Natural Selection has no answer as to why simple life forms should even arise in the first place.

The alternative is more ridiculous.

There is no "sheer creativeness". Your emotive language is blinding you to the basic facts of the situation. Take a look at your appendix, and tell me what the hell gawd was doing when he left it there.
That is how is it whether you like it or not. The alternative is more ridiculous.Which alternative? I can think of a few. The one I spoke of, that Nature functions in an intelligent way, is far less ridiculous than the idea that Nature is a mindless and aimless process that just happened to produce conscious creatures.
