Nishida quoted several times the sentences of British philosopher, B. Bosanquet in the middle period
of the formation of his own philosophical thought. The sentences express the assertion that the true
logical subject is always reality and the logical predicate is always the meaning of an idea and the judgment always appears as a revelation of something which is in reality. This assertion inspired Nishida to the build up his own unique understanding of the judgement. Bosanquet's thesis expresses that the judgment is not the connection of two abstract concepts but that the subject in judgment indicates always the reality of the actual world. Nishida's endeavor consists in the further elucidation of the structure of judgment.
The reality that Bosanquet saw behind the logical subject is understood by Nishida as the concrete universal. Nishida defines the concrete universal as the universal that embraces in itself what can be subject
without being ever predicate. According to Nishida mathematics can define their concrete universal, but the experience of facts can not define its own concrete universal. The concrete universal in the world of experience suffers the split between the subject-sphere and the predicate-sphere of the concrete universal. What is perceived by the intuition is the subject-sphere which has in itself infinite depth. Nishida owes this understanding to Bosanquet. Nishida's uniqueness consists in elucidating the predicatesphere. The infinitely deep subject-sphere is embracedby the infinitely wide universal which is the predicate-sphere.These two spheres do not coincide with each other in the knowledge of experience. But Nishida finds what bridges this split. That is the concept o f what I experience. Nishida's unique term transcendent predicate-sphere which is Nishida's definition of ego originates from this insight.
