Lincoln asks what practical difference it makes whether we embrace logical and philosophical explanations for human effort making all kinds of good things happen. He promotes the active faith involved in Mormon Transhumanism as promoting good works.
It is a good and perhaps fundamental question. I do really like his thoughts about an active faith and the concept of fully utilizing technology and scientific opportunities, and promoting the best of human effort.
I'll try and describe here the difference it makes for me.
When it comes to the resurrection and atonement of Christ, I personally enjoy the feeling of faith and the awe at the miraculous and things that are not fully explained. I can more easily love and embrace the concept of "My Heavenly Father," than I can "posthuman capacity." Perhaps we're talking about the same thing, but it's just more tiring and less enjoyable for me to try and explain my entire faith scientifically or logically.
When I pray to my Father in Heaven, I like to imagine a real, tangible person who through some miraculous process I don't (nor do I try to) understand, loves and understands me just as he loves and understands the billions of other people who must be praying to Him as well. I love the feeling that "I am a child of God," and that my literal Spirit Father loves me so much that He gave His Only Begotten Son to enable His love and grace to overcome all my weaknesses and sins to allow me to eventually live with Him forever. I'll desperately need this mercy because I cannot possibly approach the perfection He envisions for me through my own efforts.
Even with His grace, I want to and need to work hard and do my best to develop my personal capacity, and I agree with the emphasis on stretching to reach for our fullest human potential. But, often I fail, or feel weak, or need help or inspiration from a source beyond my own, or I just feel I've reached the limits of my personal capacity. At those moments, I love feeling the comfort inside that comes when I ponder and pray and sense His infinite love for me. It's a special, loving peace that sometimes includes tingles or special emotions that are hard to explain. I feel comforted, loved, motivated to do better, and want to reach out to help others. Sometimes I have sudden ideas or thoughts that help people or help solve personal problems. At those times, I just want to enjoy and feel the miraculous wonder of His Mercy and Grace without trying to explain it all through logic and philosophy. It’s an unexplained, sometimes not fully logical, but emotional connection to not just the “Christ within me” but with a real, powerful and awesome personal Heavenly Father who loves me.
Yes, I love learning, scientific discovery, and using technology to do good. However, all the logical and scientific jargon about "positive futures," “posthumans,” "posthuman capacity" and "engineered resurrections" explaining how everything could work takes away a part of the peaceful, loving feeling I get when I wrestle with difficult issues in prayer as I pour out my soul to my Heavenly Father. Maybe it’s just semantics, but the semantics make a difference to me.
Put simply, I want to feel the love.
It's harder for me feel love from or for numerous unknown "posthumans" who happened to use their own genius to eventually develop the capacity to create other worlds.
Too much logic, philosophy and scientific explanation of miracles such as mercy, resurrection, and grace can rob me of some of those special feelings that are central to my religious experience.
