Of course it is natural, but natural may include a whole lot more then the senses can perceive.
Sure, that is why instruments are so important and have allowed us to abandon non-material guesses for material explanations.
I believe intelligence can be learned, but as time goes by the quality of information and experience one lacks, or has can severely handicap one from learning intelligence in the span of a lifetime.
There are different kinds of intelligences, but the primary definition we are referring to is the ability to problem solve and understand complex concepts. Knowledge and skill can be learned but I haven't read anywhere that intelligence can be learned.
I know other animals have consciousness and I don't see that being a problem.
Yeah, it's an exceptionally common thing on earth. It's been common for over 100 million years. The typical religious-based arguments I read is that it's human consciousness that is special, and I can't see anything that supports the notion that it is. The "specialness" tends to be tied to our evolved brain and what it can do that is different than other primates. There's a sort of pettiness about these claims that bothers me from the religious, like when pretty things brag about how pretty they are. The wise never brag about how wise they are.
The fact is that even though there are varying degrees of intellect in all animals, one animal managed to gain vast potential.
There's no indication that it was intended or a goal. The human brain evolved some 200,000 years ago yet only in the last 10,000 or so did these brains start making massive progress. The circumstances were such that our history is what it is. But even with our advances look at humans today, still making war, still making poor political decisions. Still making poor decisions about health and the planet, thus the future. There's a lot of potential that is being left untapved, and in a way that could result in many millions dying from various causes, from diseases, to war, to famine, to pollution. Who knows what long term impact microplastics will have on living organisms, including humans. We are smart, just not all that wise. The book Emotional Intelligence outlines how the human brain evolved a larger neocortex, but the primitive limbic system stayed the same. So our species is saddled with a conflicted brain, one that is highly emotional, and easy to be emotional in decision making. And frontal lobes capable of promblem solving but must learn skill to function property and effectively.
I infer it based on the non physical properties.
What non-physical properties are you referring to?
I think you are overly confident that everything is physical in the most mundane way; only by looking at life through the senses.
Can you point to anything non-physical? How is it over-confident to acknowledge that all we have is physical phenomenon? I suggest it's questionable to assume anything else given the lack of evidence. And especially since the only reason to advocate for a non-physical is the traditions of religious belief that date back thousands of years.
There really should be a science of introspection. Third person observation won't reveal everything there is to know. Third person can't reveal first person properties of inner experience.
I'm not sure what you mean by this. There's quite a bit of study about brains and conscious exprience.
That's a sense perception that is your unproven assumption. The self exists beyond just being conscious.
An extraordinary claim. How's that? What part of the self is not contained solely in the brain of the individual?
Humanity does not have the whole of physics and my hunch is that existence is grander than the senses reveal.
Based on what? Could it be religious influence? Could it be a way to make religious tradition seem relevant in the 21st century?
I know that GR, and QM cannot currently be reconciled together as well.
Experts are still working on understanding and explaining how the universe functions.
Love is a constancy of being that doesn't depend on fleeting emotions that come and go. Emotions are responses to love, and other qualities of being. Emotions don't explain love. Besides also qualia doesn't model well with brain processes.
Of course emotions explain love. Love is largely a trait that is similar in many animals. Observing how a momma cat takes care of her kittens is similar to human moms. The difference is how humans will conceptualize emotions, love, commitment, obligation, etc. into complex social relationships. The love couples feel and express are idealized and ritualistic. As we know the love that many couples feel tends to fade, and even with children there is about a 50% divorce rate. Looks to me that love comes and goes.
