Do Animals Have Souls? What Judaism, Christianity, and Islam Teach

The Hebrew Bible uses the word nefesh (lifebreath/soul) for both humans and animals, and Ecclesiastes presses the point with unusual candor. The text observes that humans and animals share the same fate in death and the same ruach (breath/spirit) Ecclesiastes 3:19. The author then asks pointedly whether the human lifebreath truly rises upward while the animal's sinks into the earth — leaving the question deliberately open Ecclesiastes 3:21.

Rabbinic tradition, developed over centuries in the Talmud and later by medieval philosophers, generally distinguished three levels of soul: the nefesh (vital/animal soul), the ruach (emotional soul), and the neshamah (the highest, uniquely human divine soul). Maimonides (12th century) argued in his Guide for the Perplexed that animals possess only the lower nefesh — an animating principle tied to the body — without the rational or immortal dimension reserved for humans. Later Kabbalistic thought, especially in the Lurianic school (16th century), went further, suggesting that animal souls can undergo a form of transmigration (gilgul neshamot) and may even ascend toward higher forms through human interaction and ethical treatment.

The Torah's repeated concern for animal welfare — prohibiting cruelty, mandating rest for working animals — implies that animals possess morally significant inner lives, even if the precise metaphysics remains contested. Genesis 7 lists animals alongside humans as creatures worthy of preservation Genesis 7:8, reinforcing their dignity without resolving the soul question definitively.

Christian theology has historically drawn a sharp line between human and animal souls, though the debate is far from settled. The key text is 1 Corinthians 15:45, where Paul quotes Genesis and contrasts the first Adam — made a 'living soul' (psychē zōsan) — with the last Adam (Christ), who became a 'quickening spirit' 1 Corinthians 15:45. This framing elevates the human soul into a unique theological category tied to resurrection and divine image-bearing.

Thomas Aquinas (13th century) systematized the dominant Catholic position: animals possess a sensitive soul (enabling sensation and movement) but not a rational soul, which is immortal and uniquely human. René Descartes (17th century) took this further, controversially treating animals as mere biological machines with no inner life whatsoever — a view most contemporary Christian thinkers reject as extreme.

Protestant reformers like John Calvin largely agreed that animal souls perish with the body. However, C.S. Lewis (20th century) speculated in The Problem of Pain that domesticated animals might share in human resurrection in some derivative sense — a minority but persistent view. Jesus himself used soul-language (psychē) to describe his own anguish in Gethsemane Matthew 26:38Mark 14:34, grounding the concept firmly in personal, relational experience — something most theologians see as distinct from animal experience.

Contemporary evangelical and Catholic thinkers like Randy Alcorn and the Catechism of the Catholic Church (§2416) affirm animal dignity and God's care for creatures, but stop short of asserting animal immortality. The question remains genuinely open in mainstream Christian thought.

The Quran's explicit soul-language (nafs) is overwhelmingly directed at human beings. Quran 86:4 states that every soul has a guardian or protector over it Quran 86:4Quran 86:4, and Quran 75:26 describes the soul's departure from the body at death Quran 75:26 — both passages framed around human accountability before God. Animals are not addressed in these soul-contexts within the Quran itself.

Classical Islamic jurisprudence and theology (kalam) generally held that animals possess a ruh (spirit/life-force) that animates them, but not the morally accountable nafs that humans carry into the afterlife for judgment. Ibn Qayyim al-Jawziyyah (14th century) wrote in Hadi al-Arwah that animals will be resurrected on the Day of Judgment — not for accountability, but so that justice is rendered among them (e.g., a hornless animal receiving recompense from a horned one), after which they return to dust. This view draws on hadith literature rather than the Quran directly.

The Prophet Muhammad's reported concern for animal welfare — condemning unnecessary harm, prohibiting animal fighting, emphasizing humane slaughter — implies that animals possess a spiritually significant life that humans are morally obligated to respect. Some Sufi thinkers, like Rumi (13th century), attributed a form of spiritual longing to animals, though this remains outside mainstream juridical opinion.

So Islamic tradition's answer is nuanced: animals have a life-spirit (ruh), will be resurrected for justice, but do not carry the immortal, accountable soul that defines human spiritual destiny.

Ecclesiastes states that humans and animals share one fate and the same lifebreath, which suggests a shared creaturely vitality under God, though it does not settle metaphysical questions about an enduring soul for animals Ecclesiastes 3:19.

Ecclesiastes immediately adds uncertainty: “Who knows if the lifebreath of humans does rise upward and if the breath of animals does sink down into the earth?”, signaling an intentional openness in the text about post-mortem differentiation between human and animal life-breath Ecclesiastes 3:21.

The New Testament passages here speak about the human soul, not animal souls: Jesus says, “My soul is exceeding sorrowful,” and Paul contrasts Adam as a “living soul” with the last Adam as a “quickening spirit” Matthew 26:38Mark 14:341 Corinthians 15:45.

These passages focus on human life, suffering, and resurrection themes, and they do not directly address whether animals have souls in the cited texts 1 Corinthians 15:45.

The Qur’an affirms that there is no soul but that it has over it a protector, while one translation specifies “No human soul but hath a guardian over it,” indicating divine oversight of the human soul in this verse Quran 86:4Quran 86:4.

The Qur’an also describes the soul approaching death, but these cited passages do not state whether animals have souls, leaving the question unanswered here by the quoted verses Quran 75:26.
