A 1903 article in "The Boston Daily Globe" refers to euphoria as "pleasant excitement" and "the sense of ease and well-being". In 1920 "Popular Science" magazine described euphoria as "a high sounding name" meaning "feeling fit": normally making life worth living, motivating drug use, and ill formed in certain mental illnesses. Robert S. Woodworth's 1921 textbook "Psychology: A study of mental life", describes euphoria as an organic state which is the opposite of fatigue, and "means about the same as feeling good."
