【明報專訊】Sometimes ideas and viewpoints are dissimilar or disparate. They may have some differences or be clearly different (distinct). If two ideas have the same origin or characteristics but then move away from each other (divergence), they are said to be diverging. This leads to a dissociation and means they have become detached. A dichotomy may then occur, which is a division with two opposing units. If they are still together but are formed of dissimilar components, they are considered heterogeneous. If these dissimilar parts are unsuitable, then incongruity occurs. When standpoints or positions are opposing, they are said to be conflicting and discordant, which leads to discord. Most topics and debates produce diverse opinions; some are complete opposites (polar/polarity) and would never be able to form an alliance (incompatible). These divisions will then cause those that hold one view to rebuke or reproach the other.
