There is probably no argument by which the case for theism, or for, de — Pantheism

"A human being is a part of the whole, called by us “Universe,’ a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest — a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole nature in its beauty."

"Hence we see, that the infinite essence and the eternity of God are known to all. Now as all things are in God, and conceived through God, we can from this knowledge infer many things, which we may adequately know, and we may form that third kind of knowledge... Men have not so clear a knowledge of God as they have of general notions, because they are unable to imagine God as they do bodies, and also because they have associated the name God with images of things that they are in the habit of seeing, as indeed they can hardly avoid doing, being, as they are, men, and continually affected by external bodies. ...Very many controversies have arisen from the fact, that men do not rightly explain their meaning, or do not rightly interpret the meaning of others. For, as a matter of fact, as they flatly contradict themselves, they assume now one side, now another, of the argument, so as to oppose the opinions, which they consider mistaken and absurd in their opponents."

"Pantheism teaches that every thing is intrinsically good and pure ; all originally one with divinity, and that every appearance of wrong or guilt exists but in idea, or depends on the conventional idea entertained of it. Hence its dangerous influence on the moral life and character; for by whatever subtlety of language the meaning may be disguised, and however men may cling to a belief in the all-regulating power of conscience, yet, if this destructive principle be admitted as a ruling fact, the conduct of individuals will be considered as of slight importance, and the eternal distinction between right and wrong, good and evil, set aside, and finally rejected."

"Scientific research can reduce superstition by encouraging people to think and view things in terms of cause and effect. Certain it is that a conviction, akin to religious feeling, of the rationality and intelligibility of the world lies behind all scientific work of a higher order. [...] This firm belief, a belief bound up with a deep feeling, in a superior mind that reveals itself in the world of experience, represents my conception of God. In common parlance this may be described as "pantheistic" (Spinoza)."

"Theists believe that God and the Universe are at least in part separate and distinct beings. For pantheists there is only one all-embracing Reality: the Universe. [...] [T]he unity of the universe and nature is not just a feeling or an abstract belief: it has a solid basis in science. [...] Every single particle, every star, every being in the universe is linked by the force of gravity. A quasar on the edge of the observable universe has some effect, however small, on each of our bodies. The whole universe is a tightly woven mesh of electromagnetic radiation. Everything emits photons of energy which race in all directions. Everything is made of the same sub-atomic constituents, held together by the same forces. And everything transmutes into everything else."

"To me, nature is sacred. Trees are my temples and forests are my cathedrals."
