存在と無
The lyrics on "Dimensions" deal with philosophy. For example, on the song "Dimentia" the lyrics deal with the philosophical paradoxes and the ponderings of Sigmund Freud, Thomas J. J. Altizer, Ludwig Feuerbach and Jean-Paul Sartre about the existence of God. The song specifically quotes Altizer's "The Gospel of Christian Atheism", Sartre's "Being and Nothingness", Feuerbach's "The Essence of Christianity", and Freud's "Dialogues Concerning Natural Religion".
