Most of us, including many philosophers, are stuck in dualism; therefore, we are stuck in self view. If we believe in the existence of a self, we will reject the non-existence of the self. If we believe in the non-existence of a self, we will reject the existence of a self. Why? Because we are stuck in our normal logic that is dualism in nature.
When we believe in the non-existence of a self, we could believe that nothing exists that deserves to be called a self, or there is no self (from the beginning). When we believe in the existence of a self, we will argue that our body and experiential sense of self deserve to be called a self, and so on.
Even if we believe in both the existence and non-existence of a self, we will fall into one of the tetralemma of existence and nonexistence. We cannot go beyond them. Why? Because we are stuck in dualism.
Using our normal logic, we create many theories: True self, fake self, no self, not self, minimal self, multifaceted self, subjective self, objective self, intersubjective self, self beyond the All, unknowable self, indescribable self, ultimate self… The Buddha told us that all of these theories are just a thicket of views. They are called doctrines of self.
The Buddha cautions us that we should not affirm that “only this is the truth, everything else is false.” However, we often stick to our own beliefs and reject all the others that do not fit our beliefs. Why? Because that is how dualism works. If this is true, then it cannot be false at the same time. Something cannot be 1 and 0 at the same time. This is illogical to our normal logic.
‘All exists’: this is one extreme.
‘All does not exist’: this is the second extreme.
Avoiding these extremes, the Buddha teaches the middle way: With ignorance as condition, volitional formations,… With the cessation of ignorance, cessation of volitional formations… In other words, with this condition, that arises, with that condition, that ceases.
Seeing the arising of the world, we cannot say that it is non-existence. Seeing the cessation of the world, we won’t have the notion of existence regarding the world.
The world arises and ceases depending on condition. With condition, we can refer to its existence and non-existence. However, without condition, we cannot say anything about its existence; therefore, exists, not exist, both exist and non-exist, neither existence nor non-existence are all invalid when there is no condition.
If we refer to a conditioned self or soul then we can refer to its existence or non-existence. With this condition, we cannot say that it is non-existence. With that condition, we cannot affirm its existence.
Existence and non-existence depends on condition. Without condition, we cannot say anything about existence or non-existence. Therefore, we cannot say anything about the Tathagatha since the Tathagatha is free from all conditions. Any attempt to describe or affirm the existence or non-existence of the Tathagatha (or the Buddhist’s atman) is simply incorrect, and this is called self view.
We may have different understanding about the unconditioned or Nibbana. We may think of Nibbana as a place, a state, a thing, an event or something else. However, as I understand, Nibbana is simply a term to refer to the unconditioned. The unconditioned means that when all of the conditions are ceased, when there is no more condition left then we reach the unconditioned. Nibbana is simply the absence of all conditions, or in other words, the absence of all conditions is called Nibbana. Therefore, when we say the Tathagatha is unconditioned, I think we mean that the Tathagatha is free from all conditions, not that the Tathagatha is Nibbana or the Tathagatha is the unconditioned! Whoever attains Nibbana is simply the one who is free from all conditions.
We can try to understand this difficult concept by exploring the quantum superposition. What can we say about it? Is it beyond our normal logic?
