Absolutism doesn't mean that we know what all the absolutes are. It means that we understand that the universe is based on laws, whether we are aware of them or not, whether we understand them or not.
Absolutism often has a negative connotation, such as expressed in "My country right or wrong." Fanatics also provide a negative connotation, willing to kill the bearer of opposing views, rather than confront the possibility of being wrong.
Being willing to kill another over bumper-sticker-wisdom is the travesty of the modern world. Fanaticism is a choice to die rather than confront one's own insecurity. It is the exact opposite of all universal spiritual teaching -- the opposite of "Know thyself" and the tradition of self inquiry.
Absolutism is the knowing that all that is, is God, by whatever name you give: God, Source, The One, Natural Law, The Force. All point to an acknowledgment of the absolute nature of reality.
Absolutism does not eliminate uncertainties about choices we make, but it may provide an ultimate security, a serenity, due to knowing that all is covered in a blanket of Oneness -- the security of Love.
Under the mantel of the security of absolutism, we may also hold on to humility, taking all knowledge as tentative and subject to change, providing us ground to stand on, while being willing to listen, being willing to amend. This is the opposite stance from fanaticism
Before the earth was flat, it was round. It was round when we knew it to be flat. It is still round now that we know it is round.
Before quantum physics, Newtonian physics was the only law we knew. Now quantum physics has expanded our understanding to embrace the non linear Absolute. Quantum physics has expanded our knowledge, bringing science into the realm of consciousness research.
The absolute does not change, but our understanding does. This ability to act on what we know, yet remaining tentative about what new understanding may come, keeps humility in place. We agree to be changed as understanding deepens.
The fanatic believes that his mental position must be defended at all costs. The fanatic would rather die than allow his position to be questioned. In the end, fanatics have to make all others like themselves. This is the opposite of freedom.
On the other hand, the spiritual person embraces the Absolute with humility, knowing that any position taken is only a step on the road home. With an open mind, there is less to defend, yet the position is stronger.
Humility is the strong suit in the game of life. The face of the Absolute is seen by few, but we are all on the way. Let us journey on, knowing that the Absolute is there with open arms. The end is sure, but the journey must be taken with freedom from the known.
