What was Stephen's objection to absolutism?
Throughout many of his works, Toulmin pointed out that absolutism (represented by theoretical or analytic arguments) has limited practical value.
Why did he believe absolutism had limited practical value?
Toulmin contends that many of these so-called standard principles are irrelevant to real situations encountered by human beings in daily life.
Does he have any other beliefs regarding absolutism?
To develop his contention, Toulmin introduced the concept of argument fields.
What is the concept of argument fields?
some aspects of arguments vary from field to field, and are hence called "field-dependent," while other aspects of argument are the same throughout all fields, and are hence called "field-invariant.
Do others share or oppose his beliefs?
CANNOTANSWER.
What was his objection to relativism?
the anthropologist or relativist overemphasizes the importance of the "field-dependent" aspect of arguments, and neglects or is unaware of the "field-invariant" elements.

Question: What are the field-invariant elements?
Self-contained rewrite: What are the field-invariant elements of an argument?
