I suppose many people daydream about some idyllic, pastoral kind of Paradise - and when we are young, perhaps we believe it may potentially be attainable on this earth and during mortal life?
Over the years I have had several such daydreams - including The Shire, and Lothlorien from Middle Earth; being a married writer with kids in a rural retreat among friends; and a particular era in Concord, New England at the time of Emerson and Thoreau.
Such daydreams have a fuzzy quality, are often little more than a snapshot - or a particular mood state; and are utterly detached from the practicalities and realities of the situation - such as how it might arise, and how it could be sustained.
As I have said before; paradise implies not only an ideal place, but our-selves changed such that we would be able to enjoy it. I could not experience The Shire as in my daydream unless I was also a hobbit; nor Lothlorien unless an elf; not Concord c1840 unless I was a man of that time, place and class.
In another sense, we would have to become a better person (better in the sense of better-fitted to the daydream); and when young we tend to assume that this can and will happen. But anyone who is realistic and honest soon realizes that this doesn't happen.
We change, yes; but we don't really get better overall.
Even when we eliminate some besetting sin, or some horrible antisocial trait; this always comes at a negative cost.
That cost may be necessary, and worth paying - but there will always be a significant cost...
In his Exegesis: After listing 24 ways in which he has been changed and improved by his religious experiences of February and March 1974 - and writing some year and a half later - Philip K Dick concluded [from page 226 onward]:
The only problem is, I am in no customary sense - maybe in no sense whatsoever - spiritualized or exalted.
In fact I seem even more mean and irascible than before.
True, I do not hit anybody, but my language remains gungy and I am crabby and domineering; my personality defects are unaltered.
In the accepted sense I am not a better person.
I may be healthier (maybe not that; vide the blood pressure). But I am not a good person, even though my emotions and moods are better under control.
Maybe I just have a long way to go...
In the end, if we pursue this to its conclusion; we will realize that paradise can only be post-mortal; and that any "paradise" that does not entail the retention of our-ultimate-selves is not a paradise at all (because it would be somebody else enjoying it) - yet the ultimate selves must positively and qualitatively be transformed, in a way that never truly happens in our experience or knowledge of this world.
