A classic work which helps the reader experience their inner essence and feel the tangible presence of the spirit.
"The 'I' that we each say we are cannot be the 'I, ' except in living thinking--still unknown to us. We know only the 'already-thought, ' or reflected thought, but we are unaware of how we know it. First, we must think in order to know our own thought; but we do not know thinking." --Massimo Scaligero
This treatise, though logically formulated and accessible, proposes a task that few can probably actualize. Its thoughts are assembled so that retracing them becomes the proposed experience. This experience, insofar as it is realized, is not merely one of many possibilities, but an experience of our inner essence, which the spirit demands of us at the present time.
"True thinking cannot be the "already-thought," or reflected thought, and, as reflected, fixed in words. Nor can it be thought reflecting itself, or in the act, however conditioned it is by the form of its self-expression. True thinking is logically the being of thought, unconnected to any determined thought."
The treatise cannot be refuted philosophically, since it is based on a kind of experience that must be achieved if we wish to have a means by which to question it. However, those who are able to achieve it begin to live within a thinking that penetrates the world. It is the thinking that is the truth of all theories and of none, because it is their pre-dialectical substance.
By experiencing the thoughts presented, we can experience the power of "concentration," or the tangible presence of the spirit--the path of living thinking, the transcendence present but not cognized in each thought that we think.
