In terminology, realism refers to someone whose philosophy (e.g. philosophical realism), work (literary realism), discussions, dialogues, and or ideologies incorporate reality as closely as it is known.

Literary realism
Two leading realism authors include: Goethe (Elective Affinities, 1809) and his vicarious student George Eliot (Middlemarch, 1872). Emile Zola also is counted among realism authors. [1]

Extreme realism
The nature of what can be referred to as “extreme realism” is given by Goethe in commentary to Friedrich Schiller on unreal nature of the work of French author Prosper Crebillon: [2]

“Crebillon … treats the passions like playing cards, that one can shuffle, play, reshuffle, and play again, without their changing at all. There is no trace of the delicate, chemical affinity, through which they attract and repel each other, reunite, neutralize [each other], separate again and recover.”

In other words, to understand the nature of the passions, as modern science (knowledge) understands things, one has to come to understand (a) irreversibility and (b) the partial differential equation nature of free energy change per unit time, both in a non-supernatural (godless, spiritless, soulless, karmaless, etc.) way.

Extreme atheism
In 2014, American electrochemical engineer Libb Thims began to employ the term “extreme realism” as a synonym for “extreme atheism”, in video and discussion of the newly-launched Atheism Reviews channel, defined as someone who “embraces reality”.

Quotes
The following are related quotes:

“God and the universe, soul and consciousness, idealism, realism! I swim in a sea of forma dialectic and logic, unfortunately not with my former ease. More experienced swimmers have enticed me too often into the rapids and eddies.”
— Fritz Haber (1887), aged 19 letter Max Hamburger, Jan 23 + Feb 2 [3]
