The "law of cause and effect" states that every action (cause) leads to a reaction (effect). This principle suggests that events do not happen randomly; instead, they are the result of specific actions or conditions. For example, if you drop a glass, the cause is the action of dropping it, and the effect is the glass breaking. This law is fundamental in various fields, including science, philosophy, and psychology. In science, it helps explain natural phenomena, while in philosophy, it raises questions about free will and determinism. Understanding this law can help individuals make better decisions by considering the potential outcomes of their actions.
