Rawson on reincarnation.

There is a good deal of difference of opinion with regard to details of reincarnation. Schopenhauer, Fichte the younger, Herder, Lessing, Hegel, Leibnitz, Paracelsus, Boehme, and Hume, all were in favour of the theory of reincarnation. The reason for this is that reincarnation is a little nearer the truth than the belief that when man dies he goes to hell or to heaven.

Subjective Idealism/Immaterialism

George Berkeley (1685 –1753), also known as Bishop Berkeley (Bishop of Cloyne), was an Anglo-Irish philosopher whose primary achievement was the advancement of a theory he called "immaterialism" (later referred to as "subjective idealism" by others). This theory denies the existence of material substance and instead contends that familiar objects like tables and chairs are only ideas in the minds of perceivers, and as a result cannot exist without being perceived. Thus, as Berkeley famously put it, for physical objects "esse est percipi" ("to be is to be perceived").
