The "Reason for Reality" presented in this book is derived from non-theistic ideas, although it does not rule out theistic origins.
The prime notations use cosmological (e.g. singularities), atomic evolution (e.g. quarks to iron) and galactic evolution (e.g. biosphere development).
The formation of introspective entities in biospheres lends itself to recognition of variation in individuals and environments. Thus imperfections and overt needs of assistance are generated. These individuals ("unfortunates") and situations need to be corrected by other individuals ("fortunates") The terms unfortunate and fortunate being relativistic.
Also discussed in bio-philosophical terms are a variety of aspects related to the cancer problems. Biochemical and molecular biological mechanisms are devised.
In conclusion the reason for reality is to give an opportunity to help unfortunates.
