sceptical philosophy

To explore skepticism, we should first give a meaning definition to skepticism. So what is skepticism? I think skepticism and epistemology are inseparable. If there is no epistemology (whether thinking can know existence), there can be no skepticism. That is to say, the objective reason for the existence of skepticism lies in the subjectivity and conditionality of cognition. Cognition is human cognition after all, so the influence of subject on cognition is not only not negligible, but also may even be decisive. Many factors, such as time limitation, social standpoint, cognitive angle, knowledge structure, individual experience and subjective will and emotion, will interfere with the truth of our cognition. So that in the end, we can't reach the truth itself at all, but can only approach the truth endlessly. Why do we suspect? Valuable doubt is not doubt for the sake of doubt, but doubt for the sake of independent, deep, and truthful thinking. Doubt, in order to break the fallacy, break the false authority, do not go with the flow, establish self-positioning; is to find the certainty of the truth, do not always fall on the same problem; to have a better life.
