Welcome1:52
Meet the central question of Living Under the Sun: how can we live meaningfully when life cannot be completely understood, controlled or possessed? Discover the path from Ecclesiastes and hevel toward intelligibility, human response, Christ and hope.
Intro2:05
Welcome to the course and discover how the seven-day journey works. You’ll be introduced to the questions of meaning, uncertainty, reality and human purpose that guide everything that follows.
Initial Preface5:40
Before starting the main course, become familiar with several key ideas that will appear throughout Living Under the Sun. This short orientation introduces hevel, “under the sun,” readable-but-not-ownable reality, the Logos, participation, responsibility and grace, while clearing up some common misunderstandings before the journey begins.
In this video you will:
understand several important terms in plain language
distinguish mystery from meaninglessness and limited knowledge from no knowledge
see what the course means by participation, responsibility and grace
learn how to use the Glossary and Common Misunderstandings resources as you continue

1:12 — “Participable” / “the Logos became flesh”
“Participable” means something can genuinely be shared in or lived, not merely understood as an idea. “The Logos became flesh” is Christian language for the Incarnation: the claim that the divine Word/Son truly became human. The course is previewing a later Christian claim here; it is not saying that this claim has already been established by the earlier philosophical steps.

Day 18:34
Explore Ecclesiastes’ image of hevel — life as vapour, mist or breath — and consider why transience, uncertainty and limited human knowledge do not simply make life meaningless.
2:23 — Hevel
Hevel is a Hebrew word whose literal image is breath, vapour or mist. Although it is sometimes translated “vanity” or “meaninglessness,” CRS-01 does not use it to mean that nothing matters. Here it points to the fleeting, elusive and difficult-to-secure character of life: something can be real and good without being permanent, fully graspable or controllable.

Day 2 — The Intelligible Ground7:12
Explore the difference between genuinely understanding reality and completely mastering it. This lesson introduces the question of what makes reality intelligible and the Christian idea of the Logos.
2:59 — “Metaphysical”
Here “metaphysical” simply means asking what reality ultimately is and what it depends upon. It is not being used to mean “mystical,” “supernatural” or “spooky.” The question is moving from the fact that reality displays order and can be investigated to the deeper question of what, if anything, grounds that order.
4:20 — Ground of Being / Ultimate Source
“Ground” does not mean a physical layer beneath the universe, an impersonal cosmic substance, or merely a very powerful invisible object. It means the ultimate source upon which dependent reality relies for existing, while not itself being another dependent item inside creation.
5:07 — Logos
“Logos” is not being used here as another word for abstract logic, information or an impersonal law. In the Christian development of the course, Logos names the divine Word/Son. The concept-first explanation used in the course resources is the ultimate source perfectly known and expressed; the Christian terminology is then used to name that relation more specifically.

Day 3 — The Responsive Creature8:15
Explore the human person as a participant in reality rather than merely an observer, responding through reason, desire, relationships, choices, action and vocation.

1:50 — Logos-responsive creature
“Logos-responsive creature” is LUTS shorthand rather than a standard technical label. It describes the human person as a finite creature capable of consciously responding to reality — through reason, desire, moral action, relationship and worship — rather than merely standing outside reality as a detached observer.
5:11 — Communion, not absorption
Participation or communion means genuinely sharing in a life or good without becoming identical with its source. In the Christian account, union with God does not mean that the human person becomes God by nature or dissolves into God. Creator and creature remain genuinely distinct even in real communion.

Day 4 — The Twisted Map9:56
Our interpretation of reality is not reality itself. Explore how distorted assumptions can shape perception, identity, desire and action — and how reality can correct the maps through which we live.

2:10 — Sin as “ontological misalignment”
“Ontological” concerns being or reality itself. Calling sin “ontological misalignment” means that moral disorder reaches into how a rational creature relates to the source of its existence, life, truth and good. It does not mean sin is merely a technical malfunction, a mistaken worldview or a psychological problem, and it does not replace categories such as guilt, rebellion, disobedience or broken relationship.

Day 5 — The Source at the Site7:10
Can human beings finally repair themselves through greater effort or information? Explore the Christian claim of the Incarnation and why restoration begins through Christ rather than human self-repair.
2:20 — Incarnation
The Incarnation is the specifically Christian claim that the eternal Logos/Son truly becomes human in Jesus Christ. This is part of the Christian horizon of the course: it should not be heard as though the earlier philosophical investigation mechanically proves the Incarnation as a historical or revealed claim.
2:50 — Uncreated source / created participant
“Uncreated source” means that God is not one physical or non-physical object within creation; created reality depends upon God for existing at all. “Created participant” means that human beings really receive and live their existence and goods from that source while remaining genuinely creatures. Participation does not mean that humans are pieces of God.

Day 7A — The Enthroned Vocation7:17
Explore what follows Resurrection through the Christian claim of Ascension, understood not merely as movement into the sky but as the restoration and exaltation of human vocation in Christ.
Day 7B — Lived Union6:47
Explore the Holy Spirit as divine and personal rather than an impersonal force, and consider how restored life becomes something that can actually be participated in.
Day 7C — The Gathered Body5:17
Explore why restoration is communal rather than merely individual. Consider the Church as a real but still wounded community of participation, responsibility and correction.
Day 7D — The Restored Field7:37
Bring the restoration movement to New Creation: not escape from embodied life, but the renewal of creaturely existence, relationship and participation.

Conclusion — Living Under the Sun7:35
Bring the whole course together and return to its practical centre: a readable but unownable world, maps that require correction, truth that must be inhabited, and meaning without mastery.
Leaving Living Under The Sun3:23
This final farewell is not another lesson to master. It is an invitation to leave the course and return to ordinary life differently.
The aim of Living Under the Sun has never been to give you complete control, certainty, or a final explanation for everything. It is to help you live faithfully and meaningfully within a reality that is real, intelligible, gifted, and yet never fully ours to possess.
As you leave the course, carry the central movement with you: receive life rather than trying to master it, act responsibly without pretending to control every outcome, remain open to truth, and participate faithfully in the life you have actually been given.
You do not have to master life in order to live it meaningfully.

Requirements

No qualifications or prior knowledge are required. The course is designed for beginners. You only need an interest in questions of meaning, philosophy, faith, and ordinary human life, plus a willingness to reflect honestly on your own assumptions, experiences, and ways of seeing the world.

Description

This course contains the use of artificial intelligence for video, script and audio. All information is from the mind of Jack Robertson, Author of the Living Under the Sun Philosophy

Living Under the Sun is a beginner-level existential philosophy course exploring meaning, purpose, uncertainty, and what it means to live truthfully within the limits of human life.

The course begins with Ecclesiastes and its unusual description of life “under the sun.” Its recurring word hevel can mean vapour, mist, or breath: something real, but temporary and difficult to grasp. Rather than simply concluding that life is meaningless, we ask a different question: can life be meaningful even when we cannot completely understand, control, or possess it?

From there, the course explores whether reality can be genuinely understood without being completely mastered. We consider what it means for the world to be intelligible, and introduce the idea of the Logos as part of the Christian account of why reality is ordered and meaningful.

The course then turns toward the human person. Are we simply observers of reality, or are we participants who constantly respond through our beliefs, desires, relationships, choices, and actions?

We also explore how our understanding of reality can become distorted. Using the image of a “twisted map,” we examine how false assumptions can affect the way we see ourselves, other people, and the world.

The later part of the course develops the Christian response to human brokenness through Christ, the Incarnation, death, Resurrection, Ascension, the Holy Spirit, the Church, and New Creation.

Throughout the course, the aim is not to pretend that every mystery can be solved. Instead, Living Under the Sun develops a way of thinking that takes truth seriously while also recognising the limits of human knowledge.

No previous study of philosophy, theology, or Christianity is required. The course is designed for beginners who want to think more deeply about meaning, purpose, reality, uncertainty, death, hope, and how our understanding of the world affects the way we actually live.

Who this course is for:

This course is for anyone exploring questions of meaning, purpose, uncertainty, faith, suffering, and how to live well when life cannot be fully understood or controlled. It is especially suitable for beginners interested in philosophy, existential questions, Ecclesiastes, Christian thought, or the Living Under the Sun framework. No previous study of philosophy or theology is required.
