Right: Frontispiece of Italian physicist Galileo Galilei’s 1632 Dialogue Concerning the Two Chief World Systems, on the debated between whether the heliocentric or geocentric model is correct, showing three thinkers in “dialogue” on the question.

In terminology, dialogue (TR=103) is conversation or discussion between two or more people; often in aims to resolve some problem.

Overview
Greek philosopher Plato was one of the first to popularize the "dialogue" or Socratic dialogue method of of discussion. In his Symposium, via dialogue, e.g., he introduced the soul mate theory or split humans theory. In his circa 360BC dialogue Timaeus, supposedly following Pythagoras, introduced the semi atomic theory like proposition that ideal geometric forms serve as atoms, according to which atoms broke down mathematically into triangles, such that the form elements had the following shape: fire (tetrahedron), air (octahedron), water (icosahedron), earth (cube). [1]

In 1548, French physician-philosopher Jean Fernel, in his On the Hidden Causes of Things, situated a Platonic-style dialogue of sorts between the three fictional friends, Eudoxus, Brutus, and Philiatros. [2] Fernel’s dialogue became very influential to Charles Sherrington and his 1938 lecture turned book Man on His Nature.

Into the mid to late 1650s, English thinker Thomas Hobbes, specifically in his Dialogus Physicus (1661) and Elementorum Philosophias sectio prima de Corpore (1655), mounted a strong critique of vacuum and temperature work of Irish scientist Robert Boyle.

In 1809, German polyintellect Johann Goethe, in his famous “chapter four”, of his Elective Affinities, interjects into a dialogue on the possibility and potential ramifications on the physical chemistry modelling of love and relationships as types of chemical reactions, a discourse that actuated between the three characters: Eduard, Captain, and Charlotte, who each venture angled points of view on the matter.

In 1939, the film Ninotchka, written by Hungarian writer Melchior Lengyel (1880-1974), has a famous dialogue between the characters Ninotchka and Leon on the subject of whether or not love is romantic designation for an otherwise ordinary biological (i.e. powered chnopsological) chemical process (see: It’s a Chemical Reaction, That’s All).

In 2005, Russian-born American science fiction writer Lev Shneider, in his novel Matryoshka, initiates a Goethean Elective Affinities like dialogue between the character ZeeBrain and his pen-pal Ginnie, on whether or not a person is a molecule, whether two people in a bond are a new type of molecule, and the ramifications of this logic in the context of love, particularly in terms of stability.

In 2014, American electrochemical engineer Libb Thims initially proposed the name “Atheist Dialogues” to be the name of his new atheism YouTube channel, before settling on Atheism Reviews.

Quotes
The following are related quotes:

“There seem to be ‘laws’ [of] social systems that have at least something of the character of natural physical laws, in that they do not yield easily to planned and arbitrary interventions. Over the past several decades, social, economic and political scientists have begun a dialogue with physical and biological scientists to try to discover whether there is truly a ‘physics of society’, and if so, what its laws and principles are. In particular, they have begun to regard complex modes of human activity as collections of many interacting ‘agents’—somewhat analogous to a fluid of interacting atoms or molecules, but within which there is scope for decision-making, learning and adaptation.”
— Philip Ball (2003), “The Physics of Society”, talk delivered at the London School of Economics
