Upon the solution of this problem, or upon sufficient proof of the impossibility of synthetical knowledge a priori, depends the existence or downfall of metaphysics.
Most geometricians, chemists, mathematicians, and great scientists submit religion to reason only to discover a problem as unsolvable as that of squaring a circle.
We can't expect to solve problems if all we do is tear each other down. You can disagree with a certain policy without demonizing the person who espouses it.
The world is not something separate from you and me; the world, society, is the relationship that we establish or seek to establish between each other. So you and I are the problem, and not the world, because the world is the projection of ourselves, and to understand the world we must understand ourselves. That world is not separate from us; we are the world, and our problems are the world's problems.
