Etymology

Origin of consciousness

First recorded in 1625–35; conscious + -ness

Explanation

When you are awake and aware of your surroundings, that's consciousness. There are different types of consciousness, including social consciousness, being aware of injustices in society. The early Latin word conscius meant "with knowing," but it meant a shared knowledge, a meaning that was retained through the 16th Century. John Locke was the first to describe consciousness in relation to the individual, referring to it as “the perception of what passes in a man’s own mind." If you lose consciousness during the performance, we'll wake you up with some smelling salts!
