“Whatever exists, all the beings which constitute the undefined totality of the Universe, all things existing in the world, whatever their particular nature may be in respect to quality or quantity – the most diverse and the most similar things, great or small, close together or far apart – necessarily and unconsciously exercise upon one another, whether directly or indirectly, perpetual action and reaction. All this boundless multitude of particular actions and reactions, combined in one general movement, produces and constitutes what we call Life, Solidarity, Universal Causality, Nature. Call it, if you find it amusing, God, the Absolute – it really does not matter – provided you do not attribute to the word God a meaning different from the one we have just established: the universal, natural, necessary, and real, but in no way predetermined, preconceived, or foreknown combination of the infinity of particular actions and reactions which all things having real existence incessantly exercise upon one another. This defined, this Universal Solidarity, Nature viewed as an infinite universe, is imposed upon our mind as a rational necessity”.
Mikhail Bakunin, Philosophical Considerations
