Life force

In terms, life force (TR:5) (LH:3) (TL:8) refers to []

Overview

Vis viva

In 1686, Gottfried Leibniz introduced the term “vis viva”, aka "living force", into physics dialogue, as the quantity of the mass m of a moving object and the square of its velocity v, formulated as follows:

${\displaystyle {\text{vis viva}}=mv^{2}}$

This was a parallel to the term “vis mortua” or dead force. This term was specifically employed with reference to steel balls being dropped, rolled down inclined plains, or collided elastically with other balls, or inelastically with a clay surface.

Lebenskraft

In 1774, Friedrich Medicus introduced term lebenskraft, a portmanteau of the German lebens meaning “life” or “alive” + kraft meaning “force”, conceptualized as the force responsible for subconscious or autonomic processes, in organisms, such as digestion and respiration. This so-called "lebens force" was paralleled with the “soul”, which Medicus believed was responsible for consciousness. Hence, a person was moved or automated, according to Medicus, via a combination of the soul and a “life force”, a term alternatively as “living force” (verb form) or "vital force" (Greek based), depending on translator.[1]

Greek + German = Definition?

A diagram of Uwe Meierhenrich’s view (2012), following his study of Edward Trifonov’s 123 definitions of “life”, including those at Wikipedia, e.g. "biology", that they all “turn in a circle; elegant, but not helpful”.[2]

After Leibniz, and his Greek-based life definitions, and Medicus, and his German-based life definitions, a peculiar tendency arose to define "life" using a mixture of Greek and German words so to make a circular definition that passed as a patch description, to the average mind.

In 1797, Theodore Roose, in his Outlines of the Study of the Theory of the Life Force, e.g., defined “biology” as the study of the “lebens force” (or life force).[3]

Beliefs | Polls

In 2010, global polls showed that France had the highest rate (40%) of population disbelief in either "god, spirit, and life force".[4]
