Hey. I am just starting to learn about this Sastre dude.
And I am struggling to understand how this is not itself an absolute truth, let me explain my observation.
The absolute, as an idea, can be questioned, and it can lead to at least the following
1: There is an absolute.
2: There is not an absolute.
If 1 is the case, then you have access to this absolute, and at least one way to verify it.
If 2 is the case, then you are already at the absolute. Because saying that There cannot be an absolute, is itself an absolute!!!!!!!
In my experience, it is always "safer" to deny the absolute in favor of relativism. Because you can never know!!! what can you possibly understand a as tiny human being...?? probably not much...
On the other hand, if you as a human, manage to expand your consciousness and become infinite, then it is absolutely obvious that there is an absolute. Formless. Cosmic.
I don't think anyone that "rejected absolute truths and ideologies" would ever be openminded enough to understand what Truth entails.
I don't think Sastre or Schopenhauer have any idea of what a psychedelic insight like the ones Leo talks about might look like.
It seems like old philosophers like these, cannot come close to the depth of a true Awakening into the nature of reality.
