Nationalism is a psychological abberation, driven by insecurity. This is the message of this excellent article by Steve Taylor in Psychology Today, which I recommend reading. Nations are artificial constructs, which lead to pathological effects such as wars. The basic psychology of human beings is co-operative with their fellow human beings. The problems we now face, such as the covid19, climate breakdown, species extinction transcend national boundaries. The only future for humanity is one of global co-operation.
The impulse behind Brexit, of ‘making the UK great again’, and the similar impulse behind the Trump presidency, have been going in precisely the wrong direction, driven by the insecurity of their former working populations who have been driven to feel insecure by the economic system. The US appears to have a ‘get out of jail’ card in a Joe Biden presidency, but only if he addresses that failed economic system. The UK has got itself into a more permanent mess with Brexit, but can emerge if the co-operation engendered by a fair ‘deal’ is brought to fruition. A ‘no deal’ will be a psychological disaster for not just UK, but the whole of Europe. The insecurity generated can only lead to more problems.
Of course, nations will still need to exist in some form to organise human affairs, but only within the context of the larger groupings of which they are a part. History tells us that these are largely geographically based – China, India, various European empires, USA… or more global such as the Spanish, British and French colonial expansions. And the context of the United Nations or equivalent organisation is vital.
The charismatic and the populist leader are most suspect in this whole context. I suspect they automatically come to prominence as the collective sense of insecurity rises.
As Steve says,
Nationalism is a psychological aberration, and we owe it to our ancestors, and to our descendants — and to the other species, and to the Earth itself — to move beyond it.
