Anyone who is able to see the reality, and to see through it, knows that this world on the physical plane can never reach perfection. Yet people who think materialistically have the illusion that perfection can be achieved on the physical plane. This is the source of many other illusions, and particularly and characteristically the socialist illusion of the present age.
People’s illusions come in all shades of meaning; they are coloured by party politics and so on. People who take a liberal view of the world and of life have constructed their own ideal of the physical world and believe that if they realize this we shall have paradise on earth. All that the socialists are able to think of is how to arrange things on this physical plane so that everybody can live what they consider to be the good life, the same for everybody, and so on. Their vision of the future on this physical plane is of a wonderful paradise.
