Here is some formal study on Moral Intuitionalism:
https://en.wikipedia.org/wiki/Ethical_intuitionism#
As the aesthetic sense informs us about what is beautiful, we can analogically understand the moral sense as informing us of what is good. People with a functioning moral sense get a clear impression of wrongness when they see puppies being kicked, for example.
Views?Ethical intuitionism (also called Moral Intuitionism) is a view or family of views in moral epistemology (and, on some definitions, metaphysics).
It is at its core foundationalism about moral knowledge; that is, it is committed to the thesis that some moral truths can be known non-inferentially (i.e., known without one needing to infer them from other truths one believes). Such an epistemological view is by definition committed to the existence of knowledge of moral truths; therefore, ethical intuitionism implies cognitivism.
As a foundationalist epistemological position, ethical intuitionism is to be contrasted with coherentist positions in moral epistemology, such as those that depend on reflective equilibrium.[1]
Despite the name "ethical intuitionism", ethical intuitionists need not (though often do) accept that intuitions of value (or of evaluative facts) form the foundation of ethical knowledge; the common commitment of ethical intuitionists is to a non-inferential foundation for ethical knowledge, regardless of whether such a non-inferential foundation consists in intutions as such.[2]
Throughout the philosophical literature, the term "ethical intuitionism" is frequently used with significant variation in its sense. This article's focus on foundationalism reflects the core commitments of contemporary self-identified ethical intuitionists.[1][3]
Sufficiently broadly defined, ethical intuitionism can be taken to encompass cognitivist forms of moral sense theory.[4] It is usually furthermore taken as essential to ethical intuitionism that there be self-evident or a priori moral knowledge; this counts against considering moral sense theory to be a species of intuitionism.
