... rules are standards that determine the normative status of
concrete actions, while principles determine goals that the actions are
supposed to achieve.15 A person cannot perform
two conflicting actions, but he can undertake different goals that may be found
in conflict in particular circumstances, and nevertheless not forego any of
them. These goals may be more abstract (such as ‘‘justice’’) or less abstract (such as that ‘‘no man may profit from his own wrong’’).
Yeshayahu
Tishbi and Joseph Dan wrote similarly regarding the relationship between halakhah
and musar: ‘‘The halakhah cuts
to the minimum that the servant of God is required to do in order to fulfill
his obligation to his Creator [...] The musar literature
seeks not the minimum, but the maximum –
the path by which man will reach the zenith of religious life, of approaching
and clinging to God.’’21
Maharal (Be’er
HaGolah #6): One does not always accept the literal meaning of Agada as our
Sages said, “that one does not resolve apparent contradictions in Agada.” That
is because it is possible that the idea of the Agada was said in a concealed
manner. Therefore, there is no need to ask or resolve contradictions in Agada
since by apparently clarifying one Agada a contradiction to a different Agada
can be created. It is possible that the original problem was not a problem to those
who understand their esoteric nature. In contrast, Halacha cannot be utilized
without resolving all apparent contradictions and inconsistencies. Agada on the
other hand was not created for the purpose of learning what is prohibited or
permitted and therefore consistency is not required. By attempting to create
consistency it is possible that problematic elements will be rejected when in
fact there was never a problem in the first place to those who are experts in
Agada. That is why the Yerushalmi (Peah 2:4) states that one should not learn
Halacha from Agada - since it has not been conceptually clarified by the
dialectic process of questions and answers…
Nodah BeYehuda (161): Even
though the Yerushalmi (Peah 2:4) equates not learning practical Halacha from
Mishna, Tosefta and Agada - the reason is not the same for the three. … Medrash
and Agada were composed entirely for the purpose of teaching moral lessons by
means of allusions and allegories. Thus, they are the source of theological
information but were never intended to be used for Halacha. That is why we do
not learn at all from Agada to decide practical Halacha.
======================
Consequently problems are created when taking mussar and agada and viewing it as halacha - as we see concerning bein adam l'chavero issues such as lashon harah or tznius.
