People say “being” is “existence (cun zai 存在)” or “to be (shi 是).”
GUTUL says “being” is “name (ming 名).”
Table 1-1 shows how “being” is defined.
“xxx being” is “that which is named xxx.”
“xxx being as itself” is the material (or substance) or the existential aspect of xxx being.
“xxx being in itself” is the natural (or property) or the essential aspect of xxx being.
Since “xxx being” is “that which is named xxx” philosophically by definition, we have (1) xxx being = xxx.
Since “being xxx” is “xxx being as itself + xxx being in itself” which is “xxx” physically by definition, we have (2) being xxx = xxx being as itself + xxx being in itself = xxx.
Therefore, we have (3) xxx being = xxx = being xxx.
Hence, “being” is really a redundancy and an unnecessary convenience in our language, particularly in philosophy.
