Is everything one
Is the highest reality one thing and the world another, with you separate from both? Or is everything, including you, one? Monists say reality is one. Pluralists say many things are real. Dualists say two.
What it is
The world looks like a crowd of separate things: you, other people, trees, stones, stars. Some philosophies take this at face value. Others say that behind the appearance there is a single reality, and that the sense of separateness is partly or wholly a mistake. Monism is the name for the view that reality is, in some sense, one.
The question connects to religion as well as to science. If everything is one, then the divine, the world and the self may not be three things, but one seen in three ways.
The main views
- Monism. In its strongest form, exactly one thing exists. In a milder form, many things exist but only one is basic and the rest depend on it. Another form says that all things are of one kind, such as all matter or all mind.
- Pluralism and dualism. Pluralism says that many things exist or are basic. Dualism says that there are two, such as God and the world, or mind and matter.
- Advaita Vedanta. This Indian school, whose name means 'not two', holds that the individual self and the ultimate reality, Brahman, are in fact identical. The world appears as many things because of ignorance, and it is neither totally real nor totally unreal.
An example
A wave on the sea seems to be a separate thing with its own shape and its own journey. Yet it is the sea, moving. Someone who holds that all is one suggests that you stand to reality as the wave stands to the sea: you seem to be a separate being, but you are reality, taking a particular shape for a time. A dualist replies that the wave analogy hides the difference between a person and the thing they stand in relation to.
Why people still disagree
- It conflicts with ordinary experience. We plainly meet many objects and many people. Critics of monism say that any view which denies plurality has to explain away the obvious.
- It fits some science. Defenders point to physical unity, such as entangled particles that behave as one system, and to the sense that reality acts as one.
- How does oneness become many? For Advaita, the answer is ignorance, which raises the question of how ignorance can exist within what is one and aware. The tradition offers an answer, but not everyone finds it satisfying.
- What it means for life. If all is one, what is left of personal responsibility, and of love between distinct people? Thinkers on both sides have answers, and the question remains open.
