The losses of the natural world are our loss, their silence silences something within the human mind.

The natural cause of the human mind is certainly from credulity to skepticism.

The biology of mind bridges the sciences - concerned with the natural world - and the humanities - concerned with the meaning of human experience.

Of course, there is no reconciliation between the theory of evolution by natural selection and the traditional religious view of the origin of the human mind.

The natural world is not indestructible.

The human mind is our fundamental resource.
