Astrology is a belief that astronomical phenomena, like the stars overhead when you were born or the fact that Mercury is in retrograde, have the power to influence our lives.
While some believe in the power of astrology, some refuse to accept it because of the lack of evidence to support its point. It would be a fallacy to reject it without understanding it in-depth based on superfluous knowledge. Carl Jung, a Swiss psychiatrist, placed astrology on par with mythology in explaining the workings of the human psyche.
Astrology may seem scientific. Astrological principles, calculations, methods of making predictions are empirical, based on observations and past experiences, not derived from theoretical assumptions. It uses scientific knowledge about heavenly bodies, as well as scientific sounding tools, like star charts.
