Progressive Ideology
In 1937, Picasso created Guernica, a work of art which makes metaphysical value judgments about whether objective truth exists and can then be generally known. The purpose of the art was to protest war, but the method appealed to is surrealism--a condition where logic has been dethroned as the arbiter of truth in the world.
You can see in the reworked painting below [1] that perspectives clash, rather than triangulating toward an objective truth of the matter:
Picasso and other surrealists, such as Salvador Dali, carried forward the message of the Dada movement--ie, that "logical thought was at the root of all the world's problems." Indeed, in Dali's The Persistence of Memory, even the logic of time itself is called into question. [2]
The message itself derives from a prior worldview (a philosophy) which can be categorized as postmodern existentialism. Progressives like this worldview, and they work hard in order to indoctrinate it into children. This is because it artificially creates tensions between different people who have been made to believe that there is no truth about right and wrong.
This means that everything in the world is viewed as being merely a contest of wills and that it is the ones who feel most strongly who will get to win and have their own way, regardless of how short-sighted and narrow-minded they are.
The progressive worldview sets humanity up for endless tribal warfare. The only "good" reason to promote it would be if you expect to be a warlord--someone given unearned (unjust) power and privileges, in order to stop the threat of supposed enemy outsiders portrayed as feeling very differently than us.
The supposed existence of such an undefined threat (of other people's "feelings"; which incidentally cannot be searched and validated by third-party, objective analysis) is used in order to justify the concentration of power and wealth so as to protect the safe insiders (or in-group) from the dangerous outsiders (the out-groups).
Progressive ideology has forced the abdication of human reason and logic, and then enthroned human emotions as the new arbiter of morality and even of truth itself, but this has terrible consequences. The virtue-signalling outrage mobs seen tearing down Confederate statues are just the tip of the iceberg in this regard.
It would be better if progressive ideology was not championed so much and, instead, if there was a wide-scale return toward (or a revival of) traditional philosophy which acknowledges the importance of Reason, Beauty, and Truth.
The traditional values can lead to virtue and to its two main consequences in the world--peace and prosperity--but progressive values cannot. Progressive values only lead humanity toward a future of endless tribal warfare, and toward the arbitrary concentration of power which such warfare "justifies."
