This book is aimed to explain the creation of artworks and their evaluation, and offers a new concept of aesthetics and beauty of artworks. Following and reconstructing Peircean realist epistemology, Aesthetics is one of the three normative sciences, along with Logic (Theoretic) and Ethics, which are the three different modes of representing reality. Aesthetics is the mode of artistic representation of reality, and the created artworks are judged beautiful when proven as an aesthetic true representation of reality. Artists aim to represent reality truly, and hence, beautifully, in order to enhance our knowledge of it and to afford us insights on how to better conduct our life in society.

In On Truth and the Representation of Reality, Dan Nesher develops a new theory of truth in the framework of pragmatist theory of representation. Using the pragmatist theory of perception for the basis of his epistemological explanation of our confrontation with external Reality and how it's represented, Nesher shows that in our perceptual operations we quasi-prove the truth of our perceptual judgments. He explains how- through our proving the truth of our propositions and theories, we know that they correspond to Reality, and through our proving their falsity, we know that they don't correspond to it.
