IMHO, the perfectibility of the human is a misnomer. If we are to agree that the “perfection” of something lies in the needlessness of change (The Lord is all perfect, unchanging, un-moving, forever), and the human being is always changing, then there must be something else that is seeking perfection.
Perhaps, instead of seeking a state of perfection, something is seeking to EXPRESS it’s already realized perfection?
Perhaps evolution on the material level is merely the noumena, consciousness, seeking avenues to express its perfection of being?
I think we can agree that each of us has a center of gravity when it comes to the quality and content of our thinking; the mental sphere of our experience. I think we can also agree that this nousferous climate is causative to our “outward” experience and expression. Therefore what we accept as true in our minds, we perceive and experience as being true “out there”.
The picture of a garden as representing our mental plane is a beautiful one. We tend to a garden to ensure the healthy growth of certain plants, and remove the weeds which may be stunting the growth of the more productive plants.
I have had an experience, while gardening, where I removed all preconceived idea’s about any of the plants, and the weeds became equal to the tomato plant. Is this perhaps the “singularity” of thought in which we are to become?
