Subjectivity
This is traditionally defined as experience from one’s own point of view. That which is subjective is limited to one’s own personal feelings and experiences that other people can never fully know about because these experiences are internal to the mind. These definitions are important, because if anything can genuinely be known subjectively because it is personally experienced but at the same time there is something about this experience that cannot be genuinely known objectively because there is no way of minimizing personal biases among multiple people in a way that meets the standard for objectivity, then this would entail that radical empiricism is true and that scientism is false. There are some who claim that they have certain personal experiences that could never be fully understood objectively, such as consciousness, free will, and a sense of morality that allows them to make value judgments.
