Epistemic subject

Piaget's theory of intellectual development is a theory of competence, which means that its object is an ideal personality, a personality that most likely does not exist in nature, and if it does exist, its logical thinking is indistinguishable from the logical thinking of an ordinary individual. This ideal person is an epistemic subject, that is, an epistemic subject. just a carrier of knowledge that has no individual characteristics — no personal qualities, no gender, no motives (other than those that encourage him to learn) — and does not belong to any particular nationality or culture, and piaget's theory is devoted to it. Although the description of a child's competence in logical problem solving may not tell us anything about what the child will do if a problem situation does arise, it does tell us what the child is able to do if there are no factors that can make their actions less distinct. In his later works, piaget wrote about how the child solves real problems, and how his approaches, or strategies, use his competence. Although the epistemic subject only understands and knows events, the average person successfully copes with many tasks, often without even knowing that he has succeeded. In fact, the gap between the successful solution of the problem and its understanding is a typical phenomenon.

What the epistemic subject knows is ultimately limited to those truths that are immutable. Piaget was interested in how we come to understand many truths as immutable.

For example:

if A = B, and B = C, then the statement that A = C is not just true, but an immutable truth, and it cannot be otherwise.

The second example: the whole is necessarily larger than any part of it, and we either know this, or we come to this conclusion knowing what is the whole and what is the part, and not based on their measurement or empirical comparison in one way or another. At its core, piaget's theory is a theory that explains how we construct truths that we consider immutable, i.e., truths that must be exactly what they are and — presumably — cannot be different.
