Kevin Hermberg's book fills an important gap in previous Husserl scholarship by focusing on intersubjectivity and empathy (i.e., the experience of others as other subjects) and by addressing the related issues of validity, the degrees of evidence with which something can be experienced, and the different senses of 'objective' in Husserl's texts. Despite accusations by commentators that Husserl's is a solipsistic philosophy and that the epistemologies in Husserl's late and early works are contradictory, Hermberg shows that empathy, and thus other subjects, are related to one's knowledge on the view offered in each of Husserl's Introductions to Phenomenology. Empathy is significantly related to knowledge in at least two ways, and Husserl's epistemology might, consequently, be called a social epistemology: (a) empathy helps to give evidence for validity and thus to solidify one's knowledge, and (b) it helps to broaden one's knowledge by giving access to what others have known.These roles of empathy are not at odds with one another; rather, both are at play in each of the Introductions (if even only implicitly) and, given his position in the earlier work, Husserl needed to expand the role of empathy as he did. Such a reliance on empathy, however, calls into question whether Husserl's is a transcendental philosophy in the sense Husserl claimed.
