An alternative presentation of the π-calculus is given. This version of the π-calculus is symmetric in the sense that communications are symmetric and there is no dtherence between input and output prehxes. The point of the symmetric π-calculus is that it has no abstract names. The set of closed names is therefore homogeneous. The π-calculus can be fully embedded into the symmtric π-calculus. The symmetry changes the emphasis of the communication mechanism of the π-calculus and opens up possibility for further variations.
