Frank Ebersole's extraordinary investigations of certain key philosophical ideas behind problems in epistemology and metaphysics are the subject of this article-review. I have resisted providing what many readers will expect me to provide, namely, a critical examination of his philosophical methodology. I do question his unwilligness to say why his investigations only yield I negative results, and I do have something to say about classifying him as an ordinary language philosopher. However, my main focus is on trying to engage critically with what he actually does in his work. To this end, I provide a narrative of the investigation he carries out into the possibility of comparing the objects of perception and dreams, and I cite other works of his in support of my understanding of that investigation. Although one of his lengthiest essays seems to be devoted to an anticipation of an objection to his approach, I explain why even there he is not concerned with the question of why he always seems to get negative results. After suggesting why some of his later essays seem to be so hard to read, I conclude by saying something about what I take to be his achievement.
