Single Idea 12739

[filed under theme 11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism ]

Full Idea

Skeptics may doubt the truth of things, and if it pleases them to call the things that occur to us dreams, it suffices for these dreams to be in agreement with each other, and to obey certain laws.

Gist of Idea

If we are dreaming, it is sufficient that the events are coherent, and obey laws

Source

Gottfried Leibniz (On Perceptions [1680], A6.4.1398), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7

A Reaction

Leibniz flirted a great deal with phenomenalism throughout the middle of his career, as charted by Garber. Descartes made similar points. It is really only Berkeley who took this idea seriously.
