... + Everything !
In order to not Harm others we need:
in order to
situation and circumstance which then require
to decide what objectives to apply our
to plan how to address what we want to
with the talents and resources we have available.
The first item is knowledge,
from which all else must follow.
Knowledge includes everything that can be known.
Nothing that can be known can be excluded from the global set of knowledge.
Because we can Harm others by our ignorance
it becomes our responsibility to learn everything we can possibly learn
in order to understand how to not Harm others.
