The Problem

The Four Journeys tries to solve a large problem: how can philosophy explain reality without splitting reason, revelation, and spiritual experience into separate worlds?

Earlier Islamic philosophers gave Sadra powerful tools. Ibn Sina had argued that created things depend on the Necessary Being, God, for their existence. Suhrawardi had built an Illuminationist philosophy around light, degrees of reality, and direct knowledge. Ibn Arabi had described reality as a divine self-disclosure, where created things show the one divine source in many forms.

Sadra thinks these traditions are pointing toward one truth. Reality is not built out of fixed things that later receive existence. Reality is existence itself, appearing in many strengths, levels, and forms. Philosophy must explain that order and also show how the human soul can move through it.

In One Minute

The Four Journeys is Mulla Sadra's huge philosophical summa. A summa is a work that tries to gather a whole system into one ordered account.

Its main claim is that existence is the most basic reality. An essence is what a thing is: horse, tree, stone, person. Existence is that it is. Sadra says existence is not a thin label added to essences. It is what makes anything real at all.

The book is arranged as four "journeys" of the intellect. These journeys are not travel stories. They are stages in understanding: from created things to God, in God, from God back to the created world, and then through the created world while seeing it in relation to God. That structure lets Sadra discuss metaphysics, theology, nature, psychology, death, and resurrection as parts of one movement.

The Main Argument

Sadra begins from existence. We can define a horse by listing its features, but we cannot define existence in the same way. Any definition already assumes that something exists. For Sadra, existence is immediate, simple, and more basic than every concept we use to describe things.

This leads to the primacy of existence. "Primacy" means that existence is more real than essence. The idea of "tree" in the mind does not give shade. A real tree does. Its reality comes from existence, not from the abstract definition of treeness.

Sadra then argues that existence is one reality with many grades. A candle flame and the sun are both light, but one is weak and the other is intense. In a similar way, created things are not separate chunks of reality cut off from one another. They are different intensities of existence. God is not one being among others. God is pure, necessary, unlimited existence. Created things are dependent and limited grades of existence.

The four journeys organize the rest of the system.

The first journey moves from creation to God. It asks what being is, why existence is primary, and how the mind can move from many changing things toward the one source of reality.

The second journey is "in God with God." It treats God's existence, unity, attributes, and knowledge. Sadra wants to show that divine simplicity does not mean emptiness. God is simple because God is not made of parts, but this simplicity is the source of every perfection found in creatures.

The third journey moves from God back to creation. It explains how the world depends on God, how nature changes, and how time belongs to the very unfolding of bodies.

The fourth journey moves through creation with God. It focuses on the human soul, death, resurrection, and the afterlife. Sadra treats these not as afterthoughts but as the completion of metaphysics. To understand reality is also to understand where the soul is going.

Key Ideas With Examples

Existence and essence: Essence means "what something is." Existence means "that it is." You can understand the essence of a phoenix without thinking that phoenixes exist. Sadra says real things are real because of existence, not because their essences float around waiting to be activated.

Primacy of existence: This is Sadra's claim that existence is the ground of reality. An idea of bread cannot feed you. Actual bread can. The difference is not just a word. It is the difference between a concept and a real act of being.

Gradation of being: Existence comes in stronger and weaker degrees. A plant, an animal, a human intellect, and God are not equal cases of being. They stand at different levels of intensity and dependence. This lets Sadra hold two points together: reality is one, but the differences among things are not fake.

Substantial motion: Earlier Aristotelian philosophy usually treated substances as stable things that undergo accidental changes. An apple can become redder, warmer, or move across a table while remaining the same substance. Sadra says change goes deeper. Natural things are changing in their very substance. A human being is not a fixed object with changes pasted onto it. A life is an unfolding process from bodily life toward higher forms of existence.

The soul: Sadra says the human soul is "bodily in origin and spiritual in survival." That means the soul begins with the living body, but it can grow beyond bodily dependence through knowledge, action, and spiritual formation. A child is not born as a finished rational soul. The soul becomes more fully itself over time.

Knowledge by presence: This is direct awareness, not knowledge through a picture or definition. Pain is a simple example. You do not infer your pain from evidence; you are directly aware of it. Sadra uses this kind of idea, developed from Illuminationist philosophy, to explain how the soul can know itself and higher realities.

Resurrection and the imaginal body: Sadra wants to defend bodily resurrection, but he does not think the afterlife body is just the same physical body reassembled. He argues that the soul can produce an imaginal body. "Imaginal" does not mean unreal. It means a real level between pure intellect and ordinary matter, like the vivid body and world experienced in a dream, but with a stronger metaphysical status.

The four journeys: The journeys are a map of philosophical ascent and return. The thinker starts with the world, rises toward God, understands divine reality, returns to explain the world through that understanding, and finally understands the soul's destiny.

Why It Matters

The Four Journeys became the central work of Sadra's school, usually called Transcendent Theosophy or Transcendent Wisdom. It changed the center of later Islamic metaphysics by making existence, not essence, the starting point.

It also matters because it joins topics that are often kept apart. It treats logic, metaphysics, mystical experience, Qur'anic theology, psychology, and resurrection as parts of one account of reality. Sadra does not write as if philosophy is only argument or only spiritual practice. He thinks careful reasoning and spiritual transformation should work together.

The work also gave later Shi'i seminaries a major philosophical framework. Since the early modern period, Sadrian ideas have remained especially important in Iran and in traditions shaped by Iranian Islamic philosophy.

Proponents, Critics, and Opponents

Sadra's strongest proponents were later philosophers and theologians who accepted Transcendent Theosophy as a way to unite Avicennian demonstration, Illuminationist insight, Sufi metaphysics, and Shi'i doctrine.

His main philosophical background is Ibn Sina. Sadra keeps the Avicennian concern with necessary and contingent existence, but he changes the system by making existence primary over essence.

He also builds on Suhrawardi, especially the ideas of graded reality and direct, present knowledge. But Sadra replaces Suhrawardi's light-centered vocabulary with existence-centered metaphysics. See also Philosophy of Illumination.

Ibn Arabi is another major source. Sadra takes seriously the idea that created reality is a disclosure of the divine, but he gives it a technical philosophical form through existence, causality, and gradation.

Critics included theologians suspicious of philosophy, especially where philosophers seemed to weaken creation, bodily resurrection, or scriptural teaching. Sadra answers by arguing that his system can defend creation, resurrection, prophecy, and imamate more deeply than a purely literal or purely rationalist approach.

Later critics have also asked whether Sadra's resurrection theory is really bodily enough, since the resurrected body is imaginal rather than ordinary matter. Others question whether his unity of existence leaves enough room for real individual difference.
