Because of its ambiguous nature, it can be very hard to define emotions. Even more challenging would be to distinguish it from other sensations such as a temporary mood, or permanent sentimental trait. So with all these other terms in mind, emotion can be defined as the manifestation of the sensations we feel in reaction to our environments and situations around us, that linger for a long period of time. An easy example such as being told unfortunate news or discover something joyful can make us feel different sensations of sadness or happiness. So if these sensations we call emotions are so accurate with the occurrences we face daily, why even question its reliability? Because we, as human beings have also been taught something that would not be considered as natural as the feeling of emotions; we have also been taught morality. The ability to distinguish what we believe is ethically right or wrong, regardless or our instinctive urges, is what makes us different than other forms of life, and the reason we are even able to ask this question. We combat with ourselves in order to achieve goals, defeat life’s trials, and to pursue knowledge. So, maybe the reality of the question is, is it even possible to know when to trust emotions? Or else it may be trying to explain that emotions have limited value for knowledge acquisition if any at all.
