It depends on what you mean by “morality”. It depends on what you mean by ethics. It depends on if you are conflating personal values with law or political-ethics. It depends on if this is a category error of providing an economic perspective when it’s about politics/law. It depends on a lot of things.
So Mises wasn’t against murderers? Mises didn’t think the free market was better than socialism? Better is a form of good. Mises never decided upon these things? I find that hard to believe. I mean throwing around words like “objective moral values” and without clarification on what “scientific ought” means doesn’t help. Science is rationalization. You just rationalized this all out by putting this into words. You tried to make Mises position meaningful, giving knowledge, and concepts. In other words there is no denying you gave thought to your post, ie. science is knowledge:
"Where conception is at all applicable, it takes precedence over
understanding in every respect. That which results from discursive
reasoning can never be refuted or even affected by intuitive comprehension
of a context of meaning. The province of understanding
lies only where conception and the concept are unable to penetrate:
in the apprehension of the quality of values. In the domain
open to conception, strict logic rules: one is able to prove and disprove;
there is a point to conversing with others about what is
“true” and what is “false” and to posing problems and discussing
their solution. What has been arrived at by means of conception
must be acknowledged as established, or else must be shown to be
either unproved or confuted. It cannot be avoided and it cannot be
circumvented. On the other hand, where understanding enters, the
realm of subjectivity begins. We are unable to impart to others any
certain knowledge of what is intuitively foreknown and apprehended,
of what has not been hardened in the forge of conceptual
thought. The words in which we express it bid others to follow us
and to re-experience the complex whole that we have experienced.
But whether and how we are followed depends on the personality
and the inclination of the one bidden. We cannot even determine
with certainty whether we have been understood as we wanted to
be understood, for only the sharp imprint of the concept ensures
unequivocalness; it is to a concept alone that words can be made to
fit precisely. In this respect, understanding suffers from the same insufficiency
as all other efforts—artistic, metaphysical, or mystical—to
reproduce the intuition of a whole. What we are confronted with
in these attempts are words that can be understood in different
senses, from which a person takes out what he himself puts in. As
far as the historian describes the political and military deeds of
Caesar, no misunderstanding can arise between him and his readers.
But where he speaks of Caesar’s greatness, his personality, his
charisma, then the words of the historian can be understood in different
ways. There can be no discussion concerning understanding
because it is always subjectively conditioned. Conception is reasoning;
understanding is beholding…
Again and again those who want to obliterate the boundary
between scientific knowledge and mystical intuition in personal
experience reproach science for stopping at the surface of things
and not penetrating into the depths. One has to recognize that science
is not metaphysics, and certainly not mysticism; it can never
bring us the illumination and the satisfaction experienced by one
enraptured in ecstasy. Science is sobriety and clarity of conception,
not intoxicated vision.
It is true, as Bergson has seen with unsurpassed clarity, that
between reality and the knowledge that science can convey to us
there is an unbridgeable gulf.45 Science cannot grasp life directly.
What it captures in its system of concepts is always of a different
character from the living whole.46 One may therefore, if one wishes,
even call it dead, because what is not life is death. But if one thinks
that one has thereby pronounced an unfavorable judgment on science,
one is mistaken. One can call science dead, but one cannot say
that it is not useful. It is indispensable in a double sense: first, as the
sole means that can lead us to whatever measure of knowledge we
can attain at all; and then, as the only foundation for an action that
brings us closer to the ends at which we aim. Whether we see the
greatest value in wisdom or in action, in neither case may we scorn
science. It alone shows us the way both to knowledge and to action.
Without it our existence would be only vegetative." - [Mises; “Epis. Pro. of Economics”]
What is intuitive, ie. understanding according to Mises due to the German usage as he explains, is that which can’t be explained, put into thought, in other words is not conceptual. But what is conceptual is science. Thought and knowledge are science. Mises doesn’t differ from Aristotle on this point. I have knowledge and take thought on what differentiates bad relations from good relations in the sense of ethical-law. It is a continual discovery as all knowledge is. Axioms and logical deductions based on scarcity and property help bring the focus to what conflicts need investigated, etc, etc…
