I've copied this from another thread, on another forum. It's my own work, and my own ideas - insofar as anything is. The latter part was produced in reply to a scientologist and the references left in. While it does not specifically address your question, I think it has significant bearing on the subject. I hope it helps.
The simplest of organisms is crafted, in relation to reality, by the function or die algorithm of evolution. Atom by atom, its physical form is judged worthy or unworthy of existence. Judged worthy, the organism replicates and passes on its worthiness to subsequent generations.
So, we can describe an organism, like a plant, that survives merely as a function of its pysical form as having functional intelligence. All organisms possess this trait - for if they did not thier bodies would not function and the orgaism would die, and the species die out. But animal life-forms particularly are characterised by a second kind of intelligence.
All life, in the beginning was merely functionally intelligent - but by a process of random mutations that favoured or disfavoured continued existence, limbs and sensory organs developed. This led to a new kind of intelligence. Behaviours, however nominally chosen were now the subject to the function or die algorithm of evolution. Behaviours conducive to survival were promoted, and those non-conducive discouraged by death and extinction.
For many hundreds of millions of years, behaviorally intelligent animals fought and flew, hid and hibernated, built nests and bred on instinct - but acting in the course of the ingrained avoidance of threat and harm, seeking food and breeding opportunity within the spatial and temporal reality of the environment - one animal developed a new form of intelligence.
Very gradually, acting in relation to the spatial and temporal reality of the evironment, judged always by the function or die algorithm of evolution - the potential for revelation built up in homo sapiens. It may have been nothing more than a footprint in the mud that triggered the realization, but one day dawned in which it occured to man to ask: 'Who made this?'
Once that question occured it could be applied to anything. Who made me? Who made the world? Perhaps more importantly, it raised another question: What can I make?
About 35,000 years ago in Europe, suddenly, and without any gallery of clumsy attempts to serve as precedents, art appears to flourish as if from nowhere. Described by writers such as Shreeve and Pfieffer as a 'creative explosion' - this sudden occurance of art marks the dawn of intellectual intelligence.
So, we have three kinds of intelligence, functional, behavioural and intellectual - all of which are embodied by human beings, and only by human beings. In much the same way that a plant must be functionally intelligent, and an animal both functionally and behaviourally intelligent, we human beings must be intelligent in all three senses in order to survive and prosper.
Scientifically valid knowledge has a spiritual value that is not at all magical, but follows from the dynamics laid out below. In much the same way that the simplest of organisms had to be physically correct in relation to reality in order to function, and the behaviours of animals in relation to reality was either conducive to survival or not, I believe we intellectually aware animals must accept and act in relation to scientifically valid knowledge of reality in order to survive and prosper.
I'm sorry for seeming so wary, but I can't tell you how dangerous and distasteful I find religion in general. I think it the root cause of the world's ills. I don't know much about scientology - but what I have heard can't be right, can it? Alien overlords, volcanoes and migrating spirits.
I think we should put aside ideas like religion, nation and capitalist economics - that are not scientifically justified, not valid of reality, and thus direct our actions at odds with reality. It's because we act in the course of such false ideas that the world is in the mess it is. The human species is divided into groups defined by thier own sacred lies - each grabbing as much as they can for themselves, ignorant to the fact that we are all the same species inhabiting the same planet.
I think we should have a global government constitutionally bound to scientific understanding, using scientific knowledge and cutting edge technology to balance human welfare and environmental sustanability.
I note that what I've heard about scientology retains many of the features of traditional religions - a God figure, immortal spirits, and presumably therefore a purpose in life bearing upon an afterlife of some kind.
Even if scientology quietly accepts evolution, for me, this is inimical to the spiritual connotations of accepting scientifically valid knowledge of reality.
In scientific terms, it seems, the individual dies and the species lives on. In life therefore, it is the rational purpose of the individual to ensure the continued existence of the species. It is via the species - thousands of generations struggling to survive and breed and know, that we enjoy our ability to think and feel, that we enjoy reading, writing, architecture and art. In short, it is the species that's eternal and the individual is temporary, it is the species that develops knowledge and technology - it is to the species we make our incremental individual contribution, and the species that carries forth our legacy.
Spiritually, this perspective both honours and humbles the individual, binding the individual to the species. We have worth, but not too much, we are showered with gifts - and return them in kind. We have purpose, truth, reasonable expectations that follow from accepting the scientifically defined reality.
Further, there is a sane and legitimate purpose for government. It is to discover and employ knowledge and technology to provide for human welfare and secure the continued existence of the species.
I find this more spiritually profound than any religion I've encountered. There are no articles of belief, no God or immortal souls, and yet it is a better answer to all the spiritual questions - and also political and economic questions, to which we have so many answers, and none of them true.
