Emotions have been derided in many cultures, including the West. There are no neutral emotions. Emotions act as positive and negative inducements to avoid or pursue particular courses of action. Negative emotions include fear, anger, hatred, jealousy, suspicion, pain, disgust, annoyance, etc. Positive emotions include joy, elation, contentment, etc.
Humans are highly social animals.
It should not be surprising that humans appear to develop socially-related emotions that do not seem to appear in other animals. This implies that socialized emotions arise when an individual establishes the ability to conceptualize self versus other. Emotions arise only because of appraisal . However, it is important to recognize that not all appraisals arise from conscious thought. Many or most appraisals are unconscious.
