He was a doctor, philosopher, and physicist from the 19th century. He is usually considered the father of psychophysics, even though Ernst Heinrich Weber, his tutor, was the first person to scientifically approach the field. This science aims at investigating the mathematical relationship between environmental stimuli (physical event) and sensations (psychological event) through experimental procedures, as those outlined in his 1960 book entitled Elemente der Psychophysik (Elements of Psychophysics), vol.2. Weber's law, also sometimes named Weber-Fechner's law, is central to this theory. It was formulated by Ernst Heinrich Weber, and then explained by Fechner in logarithmical terms. Both laws delve into the same aspects and only differ in the way they are formally expressed. This is partly the reason for Fechner being perhaps improperly credited as the father of psychophysics. It is more precise to say that Fechner utilized the data obtained by Weber during his experiments about discrimination threshold across sensory organs and Weber's law to formulated the Fechner's law (or Fechner's scale). It states that, for "the intensity of a sensation to increase in arithmetical progression, the stimulus must increase in geometrical progression." that behavior was mostly automatic and ideas of action produced the action, guided by mental processes and the focus of attention.
Any belief or idea must be judged by its consequences and its usefulness. Even unscientific ideas are useful if they can contribute anything at all.
