Probably a tough question, but how do you then define intelligence, since you say that intelligence may be the rudimentary way of nature?
To me personally I perceive that certain things to me have an intelligent design. This design is innate within the body or structure.
I am not sure if I have ever told people here but I am a (modest) 3D and 2D graphic artist. I have been studying vector geometry for a little over 20 years.
This 3d design knowledge I have accumulated should at least give me a voice when it is in this regard to "intelligent design". Not that I am saying that what I design is intelligent or that my opinion about intelligence is relevant but I believe it to be relevant.
My first object that occurs nearly everywhere in our universe is the sphere. Is the sphere intelligent? Well our brains are encased within a sphere. Nature is full of spheres. Is a sphere intelligent? Well it can be...
Pi being innate within the sphere represents an infinite singularity. Our entire universe is pi within a sphere.
My second object is the cube. The cube is also obviously a great object, with the cube you build the pyramid..
Third the pyramid... The pyramid is the catalyst to another form of objects. Objects we call Hieroglyphs they evolve into symbols, characters, math and nebula of philosophy, thought and spirituality.
Since humans are formed by these spheres, shapes, symbols, words... we thus inherit their primal wisdom, nature and philosophy they impart...
Hope you like my art.
Thanks for the question RST
