“It does not pay a man to exist until the age of Methuselah by making his days indolent and useless. The more this is reflected upon, the more the reflector will desire to undertake meaningful and useful actions, the more they will have lived.”

Entry in Tolstoy's Diary http://www.linguadex.com/tolstoy/chapter1.htm (1 November 1910)
Context: God is the infinite ALL. Man is only a finite manifestation of Him.
Or better yet:
God is that infinite All of which man knows himself to be a finite part.
God alone exists truly. Man manifests Him in time, space and matter. The more God's manifestation in man (life) unites with the manifestations (lives) of other beings, the more man exists. This union with the lives of other beings is accomplished through love.
God is not love, but the more there is of love, the more man manifests God, and the more he truly exists...
We acknowledge God only when we are conscious of His manifestation in us. All conclusions and guidelines based on this consciousness should fully satisfy both our desire to know God as such as well as our desire to live a life based on this recognition.

Darwin Among the Machines
The Note-Books of Samuel Butler (1912), Part III - The Germs of Erewhon and of Life and Habit
Context: Day by day, however, the machines are gaining ground upon us; day by day we are becoming more subservient to them; more men are daily bound down as slaves to tend them, more men are daily devoting the energies of their whole lives to the development of mechanical life. The upshot is simply a question of time, but that the time will come when the machines will hold the real supremacy over the world and its inhabitants is what no person of a truly philosophic mind can for a moment question.
