Superstition is the fear of what is unknown and mysterious. It is the belief that certain events bring good or bad luck which cannot be explained by reason or science. In short, superstition means unkown belief. Superstition is a worldwide phenomenon. People in every country believe in one or the other superstition.
Superstitions have come down to us from ancient times. Primitive people knew little to nothing about the wonders of science. They were at the mercy of natural elements. They did not understand the causes of physical changes taking place around them. They respected and worshipped the force of nature like the sun, the moon, fire, wind, water, storms, etc. They believed that diseases were caused by the wrath of gods as well as evil spirits. They tried to satisfy the gods with offerings, prayers, sacrifices, etc. They tried to ward off evil spirits by offering sacrifices. Sacrifice of birds and animals to please the gods and goddesses and to atone for one's sins in a common practice. Thus, it is fear which gave rise to superstition.
Superstition works hand in hand with religions and cultures around the world. For instance, as I read in Things Fall Apart, the Ibo culture killed twins; for they feared they were cursed. To make sure it did not happen again, they kill twins. Now, in today’s world, most Catholics would see that as an injustice, but we have to realize that the Ibo people did not have biological knowledge. In a sense, they killed twins because they did not know anything about them.
