717:. He felt the thrill of life everywhere, in plants, earth, stars, the total universe. Fechner was a panpsychist; he viewed the entire universe as being inwardly alive and consciously animated, instead of being dead “stuff” as accepted by most of his contemporary colleagues, who had become devotees to what was becoming known as material science. Yet he based his panpsychism on a well thought out description of consciousness as waves. He believed that human beings stand midway between the souls of plants and the souls of stars, who are angels. God, the soul of the universe, must be conceived as having an existence analogous to human beings. Natural laws are just the modes of the unfolding of God's perfection. In his last work Fechner, aged but full of hope, contrasts this joyous "daylight view" of the world with the dead, dreary "night view" of

The conference is now scheduled to include 22 October to allow psychophysicists to celebrate the anniversary of Fechner's waking up on that day in 1850 with a new approach into how to study the mind. Fechner Day runs annually with the 2021 Fechner Day being the 37th. It is organized annually, by a different academic host each year. During the pandemic resulting from COVID-19, Fechner Day was held online in 2020 and 2021.

The law has been found to be immensely useful, but to fail for very faint and for very strong sensations. Within its useful range, Fechner's law is that sensation is a logarithmic function of physical intensity.
