What is agnosticism? A definition
Etymology: from Greek agn˘stos (ignorant), gnosis = knowledge.
The word agnosticism was created in 1869 by Thomas Huxley, British naturalist (1825-1895) who took inspiration from the ideas of David Hume and of Emmanuel Kant. Agnosticism is a philosophy that declares absolute, divine, metaphysics, and more generally what cannot be grasp by experiment, is inaccessible to the human mind and to perception. Consequently, the existence of God cannot be proven. Agnosticism professes a complete ignorance about the profound nature, the origin and the destiny of things. It is a form of skepticism applied to metaphysics and theology.
Already present in the Ancient Greece, agnosticism developed much in the 18th and 19th centuries because of the progress of science that provided experimental results contradicting the religious dogmas and the Holy Scripture like Bible.
God being unknowable, the agnostic cannot come to a conclusion about his existence and consequently considers that it is useless to worship him or to submit to revealed morals that should have been dictated to men.
Buddhism and Jainism are agnostic religions. Protagoras, Democritus, Hume, Emmanuel Kant, William James, Herbert Spencer, Albert Einstein were agnostic.
