„[I]t is impossible that each of the elements should be infinite. For that is body which has interval on all sides; and that is infinite which has extension without bound.“

— Aristotle
„[B]ecause that which is finite is always bounded with reference to something… it is necessary that there should be no end… [N]umber also appears to be infinite, and mathematical magnitudes, and that which is beyond the heavens. And since that which is beyond is infinite, body also appears to be infinite, and it would seem that there are infinite worlds; for why is there rather void here than there? …If also there is a vacuum, and an infinite place, it is necessary that there should be an infinite body: for in things which have a perpetual subsistence, capacity differs nothing from being. The speculation of the infinite is, however, attended with doubt: for many impossibilities happen both to those who do not admit that it has a subsistence, and to those who do. …It is …especially the province of a natural philosopher to consider if there be a sensible infinite magnitude.“
— Aristotle
„[T]he infinite is in capacity. That, however, which is infinite in capacity is not to be assumed as that which is infinite in energy. …[I]t has its being in capacity, and in division and diminution. …[I]t is always possible to assume something beyond it. It does not, however, on this account surpass every definite magnitude; as in division it surpasses every definite magnitude, and will be less.“
— Aristotle
„[H]ow will one part of the infinite be above, and another below? Or how will it have extremes or a middle? Further still, every sensible body is in place; but the species and differences of place are upward and downward, before and behind, to the right hand and to the left: and these things not only thus subsist with relation to us, and by position, but have a definite subsistence in the universe itself. But it is impossible that these things should be in the infinite: and… that there should be an infinite place. But every body is in place; and therefore it is also impossible that there should be an infinite body. …[T]herefore …there is not an infinite body in energy.“
— Aristotle
„To sustain the belief that there is no God, atheism has to demonstrate infinite knowledge, which is tantamount to saying, “I have infinite knowledge that there is no being in existence with infinite knowledge“
— Ravi Zacharias
„The infinite… happens to subsist in a way contrary to what is asserted by others: for the infinite is not that beyond which there is nothing, but it is that of which there is always something beyond. …But that pertaining to which there is nothing beyond is perfect and whole. …that of which nothing is absent pertaining to the parts …the whole is that pertaining to which there is nothing beyond. But that pertaining to which something external is absent, that is not all …But nothing is perfect which has not an end; and the end is a bound. On this account… Parmenides spoke better than Melissus: for the latter says that the infinite is a whole; but the former, that the whole is finite, and equally balanced from the middle: for to conjoin the infinite with the universe and the whole, is not to connect line with line.“
— Aristotle
„Woman has suffered for eons, and that has given her infinite patience and infinite perseverance.“
— Swami Vivekananda
„I could be bounded in a nutshell and count myself king of infinite space.“
— William Shakespeare
„Christianity preaches the infinite worth of that which is seemingly worthless and the infinite worthlessness of that which is seemingly so valued.“
— Dietrich Bonhoeffer
