What I will say is that nowhere in evolution is there 'no purpose' to life, nor is there purpose. Evolution is not an entity. Evolution is a method or system by which organisms continue on, natural selection is the way that this works most effectively in a changing and stable environment (some environments are stable, some are not, see the red queen hypothesis for more information regarding the outcome of different environments on parasites, asexual reproduction and sexual reproduction). The purpose of life from a purely biological standpoint, is to survive and produce viable offspring that can further your genetic makeup for generations. So in essence, the biological standpoint would place the continuation of one's genetic makeup as the sole purpose. If you mean to ask what the purpose of life is on a grand scale, I ask...does it matter? This is my first question because you can't delve into purpose and meaning on a grand scale immediately. We have to conclude whether or not it matters what the end result of all that is and will be, is important, or if there would need to be a purpose. To that I say it doesn't matter. Whether the universe has no sentient purpose, or does, is irrelevant to us, because we are so small and insignificant that we will never really take part in anything on such a massive scale. Our minute lives will not change or alter if we discover that the universe and all of time has no purpose. Nor will our lives change if we discover that the universe and all of time has a complex purpose. Our lives are small in comparison to time. Humans live, on average, about 80 years. When we examine the time line of the universe, 80 years is merely a microscopic piece of time that on its own is meaningless, in the way that a speck of dirt is meaningless to the whole of the earth. It would be pointless for a speck of dirt to base it's life or existence on the purpose of the earth, as it's presence is neither felt nor missed. So if you're asking what evolution (because you seem to think we derive all values from evolution for some reason) has planned and what is the purpose of all time and the universe, I say it's irrelevant. A curiosity, certainly, and one I think we should examine, but it's not going to alter or change the fabric of anyone's life if we discover it.
As far as purpose is concerned. There is no purpose to the universe because the universe is not sentient. It has no goal in mind because it is not sentient. This is not a problem, but a freedom. Consider, if the universe has nothing in mind, this gives us the opportunity to find our place, our individual place, within the world and define ourselves based on how we would that like world to look. If we think of the universe as a pond. A pond has no purpose. A pond is a bowl of water that sustains life, but it has no goal, no purpose mind. It simply is. The fish within it, the algae, the bacteria, the microscopic organisms, are all that is within the universe (if the universe is like a pond). The fish do not define their lives based on the goal of the pond. That would be silly. The fish define their lives based on that which is around them. Their goals, their desires, their motivations, define their purpose in life. Likewise, we define ourselves within the context of our fish bowl. We look to that which is around us, the devastation, the hope, the pain, the happiness, and with our own motivations, we define ourselves and therefore our purpose in life. What are goals besides desires to do something. It is all this which creates purpose on a grander scale.
Bravo, Mande!! Bravo!
