It's a contradiction in terms, isn't it? Can a left wing person or a left wing principle ever be thought of as wise? I don't think so and the reason is that leftism is an entirely secular ideology. Wisdom is surely a spiritual thing. It must be as it goes beyond logic, reason and, particularly, ideology. We may talk about the wisdom of crowds but that is really a misuse of the word. It just means a kind of natural instinct. Even the wisdom of age is just knowledge gleaned from experience. But true wisdom is perception into the heart of spiritual reality and it cannot be in any way associated with leftism which only relates to social and economic matters, in other words, worldliness. I realise there exist spiritual and religious people with left wing views but I see that as an inconsistency in them, an inability to understand the reality of spirit. It's rather like serving God and Mammon. One of them has to fall by the wayside. A spiritual leftist will always have one foot in this world. He is always grafting his spirituality onto his worldliness rather than taking everything from true spiritual perception.
I am not saying that the political right is in any way wise. That's obviously not the case but the point is that wisdom accepts the primacy of the spiritual world and leftism actually arose as a specific rejection of that. Check your history if you don't believe me. Wisdom is neither left nor right but leftist principles are a categorical denial of wisdom which is based in the reality of God as God and not as a humanist reconstruction of God.
Another point I would make to support this argument is that wisdom is hierarchical whereas leftism is rooted in egalitarianism. That is almost its defining principle. It leaves out the transcendent but wisdom derives from knowledge of transcendental reality.
This may seem a trivial thing but I see it as pointing to something very significant and that is the fundamental emptiness, even inhumanity, of leftist thought. It lacks, it cannot ever have, wisdom and therefore it only touches the most superficial level of the human experience and appeals to the most basic desires and ambitions of the human soul. But today we are ruled by leftist principles. Where are they taking us?
Added note: It might be thought that one could write a similar piece putting the word right in place of left but the reality is that the secular right only exists as an opposition/reaction to the left which was the initial disruptive ideology and therefore is part of the same anti-spiritual dynamic. However, to the extent that it does seek to preserve some vestiges of spiritual understanding, or what would derive from that, it has some small connection to the ground from which wisdom arises.
