We tend to assume - following decades of mass media propaganda - that 'imagination' is always a good thing. Probably, that was the case in the past, when imagination was used to 'to hold, as 'twere, the mirror up to nature' - that is, to imagine variants based-upon the natural.
But since the Romantic era, imagination has extended beyond nature, and from the early 20th century has become autonomous. From the early 20th century, with modernism, surrealism, Dadaism etc - imagination became often a parody, subversion or inversion of the natural.
Furthermore, as modern Man became alienated from the divine and spiritual (that is; at first able to ignore, then unable to perceive, the divine and spiritual realms) this cut-off imagination became reality.
So that in the modern, official and mass media, legal and corporate world - un-real, aspirational, asserted and enforced ideas very rapidly become normalized, accepted and then (to all intents and purposes) 'real'.
In other words, humans now - as a matter of mundane everyday practice - imagine and make their own reality. The world is convulsed and organized according to these imagined and made realities such as the birdemic, antiracism, climate emergency and the trans-agenda.
Apparently any-thing - any statement, any morality, any imperative, can be made-real now, and generally accepted as real - with little or no strain or sense of dissonance - even when it is a complete fabrication or an inversion of the natural.
Indeed; that official-reality is a total invention or an inversion of natural-reality is generally taken to indicate its moral superiority (consequently; to privilege the natural is termed 'fascism'; and is demonized and suppressed).
From this we may see that modern Men are so constituted that they will believe what they imagine; and they can be induced to imagine almost anything - especially by means of the mass media with its combination of fake-news, gossip and ideologically-shaped entertainments.
And people do not distinguish between sources of imaginations and assertions - and seldom recall or discern-between the provenance of 'knowledge' - so that beliefs are as likely to be shaped by overt fictions (a movie) as by supposed facts (taught at school).
(Although, with institutional convergence - all sources of imagination/ fact are being forcibly harmonized to the leftist, materialist, anti-Christian ideology.)
People are psychologically-made such as to privilege this media world as objective and primary, because it is widely-shared and enforced by the powerful - and they subordinate and ignore their own conscience, observations and reasoning, because these are (merely) private.
In sum - Modern Man imagines his reality; and his imagination is fed to him by the mass media; so, for modern Man; reality is whatever assumptions the mass media is currently operating on.
(And by 'currently' I mean 'the last few days' - and today's mass media assumptions may be the opposite of last week's, or the assumptions may imply the opposite of the media interpretation - but none of this matters: today's assumptions rule whatever.)
This is why the media can report as reality un-natural phenomena such as the imagined birdemic plague or climate catastrophe, can invert racial and sexual realities, can state that men and women are flexibly- and wholly-interconvertible - and will be believed; to an unrestricted degree... To the extent of structuring and administering the whole world policy and human micro-interactions alike.
Life is made, and re-made, on the basis of these (and any other potential, equally arbitrary) imaginations.
The capacity to make imagination into reality is thus a double-edged sword which pushes the world towards extremes of good or evil. Good imaginations can be made real - but so can evil imaginations; and indeed imagination can abolish or invert the distinction between good and evil.
Armed with this power; Man is called-upon, each as an individual, to imagine the good - and to eschew the evil; to imagine the beautiful and true and coherent...
But in practice, the opposite has happened.
Man has refused to acknowledge or exercise his power to imagine God, good and divine creation; has refused to imagine a living and conscious universe in which each of us has an unique contribution to make...
And therefore has opened himself to become a passive conduit for the imaginations of the evil powers who have taken-over the public world .
And this remains un-recognized because of Man's capacity to imagine evil as Good; and undiscerned because of Man's willed self-subordination to external, evil-aligned, values.
