首楞嚴義疏注經 3.240

3.240

引例無知破也。從味所生，豈合名識？故云識自為味。設許名識，亦不自甞，引例可見。

This refutes it by citing the example of insentience. How could what is produced from taste be properly named consciousness? Hence it says: 'consciousness itself would be a taste.' Even if granted the name of consciousness, it also would not taste itself; this can be seen by citing the example.
