Biosphere Quote by James Lovelock
““Gaia is a thin spherical shell of matter that surrounds the incandescent interior; it begins where the crustal rocks meet the magma of the Earth’s hot interior, about 100 miles below the surface, and proceeds another 100 miles outwards through the ocean and air to the even hotter thermosphere at the edge of space. It includes the biosphere and is a dynamic physiological system that has kept our planet fit for life for over three billion years. I call Gaia a physiological system because it appears to have the unconscious goal of regulating the climate and the chemistry at a comfortable state for life. Its goals are not set points but adjustable for whatever is the current environment and adaptable to whatever forms of life it carries.””

![“[Religious belief is] outmoded and ridiculous. [Belief in gods was a] worn out but once useful crutch in mankind's journey towards truth. We consider the time has come for that crutch to be abandoned. It is a vacuous answer... To say that 'God made the world' is simply a more or less sophisticated…” quote by P.W.
