Etymology 1
Original image of a logistic curve, contrasted with a logarithmic curve.

From French logistique, from Ancient Greek λογιστικός (logistikós, “practiced in arithmetic; rational”), from λογίζομαι (logízomai, “I reason, I calculate”), from λόγος (lógos, “reason, computation”), whence English logos, logic, logarithm, etc.; modern mathematical use influenced by related logarithmic.

Sense of “logistic function” by Pierre François Verhulst (1845) in French, then borrowed into English.[1] Verhulst does not explain his choice of naming, but he contrasts it with the logarithmic curve (also from λόγος (lógos)), and it is presumably by analogy with arithmetic and geometric (other divisions of mathematics), as his discussion of arithmetic growth and geometric growth precede his discussion of logistic growth.[2]

The term logistic and logistical also found occasional mathematical use in English prior to 1800, from the same Greek origin.

  2. Verhulst first refers to arithmetic progression and geometric progression, and refers to the geometric growth curve as a logarithmic curve (confusingly, the modern term is instead exponential curve, which is the inverse). He then calls his curve logistic, in contrast to logarithmic, and compares the logarithmic curve and logistic curve in the figure of his paper.
