Esse est percipi

 ---

Our consciousness that reality - and ourselves - exist is constructed by our brains, carefully shielded and entombed within the encapsulating dome of our thick skulls. The slender evidence of reality is no more than coded pulses on afferent nerves. A mighty pyramid balanced on its point.

Does the squirrel exist when the cat has finished watching it?

And so on.

Mind Over Matter? Not All Idealism is Created Equal: Berkeley vs. Hegel

(Published: March 31, 2025)

Ever pondered the nature of reality? Does the world exist independently of our minds, or is consciousness the foundation of everything? Philosophers who lean towards the latter are called idealists, believing that reality is fundamentally mental or spiritual. But even within idealism, there are vastly different flavours!

Two giants of idealist thought are George Berkeley and G.W.F. Hegel. Both argued against a purely material view of the universe, but their own visions of a mind-based reality couldn't be more distinct. Let's dive into the fascinating differences between Berkeley's Subjective Idealism and Hegel's Absolute Idealism.

Berkeley: If a Tree Falls in the Forest and No One's Around... Does it Exist?

George Berkeley (1685-1753), an Irish bishop, offered a radical and elegant solution to questions about mind and matter. His famous maxim: Esse est percipi - "To be is to be perceived."

• The Core Idea: Berkeley argued that reality is composed solely of two things: minds (or spirits) that do the perceiving, and ideas (the sensations, thoughts, and objects) that are perceived.
• No Independent Matter: That solid table you're sitting at? For Berkeley, it's not some mysterious underlying material substance. It's a collection of ideas – the sensation of hardness, the visual appearance of wood grain, its shape – existing in a mind. If no mind perceives it, it simply doesn't exist in that form.
• Where God Comes In: Berkeley wasn't suggesting your desk vanishes when you leave the room! He solved the problem of continuity and objectivity by positing an infinite, omnipresent mind: God. God perceives everything, all the time, thus holding reality in consistent existence.
• Why "Subjective"? His idealism is often called "subjective" because the existence of objects (as ideas) is dependent on a subject (a mind, whether finite like ours or infinite like God's) perceiving them.

Hegel: Reality as the Grand Unfolding Story of Spirit

Fast forward about a century to G.W.F. Hegel (1770-1831), a towering figure in German philosophy. Hegel also believed reality was fundamentally spiritual, but on a vastly grander, more complex scale.

• The Core Idea: For Hegel, reality is the dynamic, rational process of a single, all-encompassing entity called Absolute Spirit (Geist - often translated as Mind or Spirit) coming to understand itself. This isn't just a mind, but the totality of reality – including logic, nature, human consciousness, history, art, religion, and philosophy – understood as a unified, developing system.
• What About Nature and Matter? Hegel doesn't simply deny the material world like Berkeley. Instead, he sees nature as the Absolute Spirit in a state of "otherness" or externalization. It's a necessary stage in the Spirit's journey towards self-realization. The physical world is real, but its ultimate meaning and reality are found within the context of this overarching spiritual development.
• History Matters: A key element for Hegel is history. He saw human history as the progressive unfolding of Spirit's self-consciousness, driven by a dialectical process (the clash and resolution of opposing ideas – thesis, antithesis, synthesis).
• Why "Absolute"? It's "absolute" because it describes a single, total, all-inclusive reality (the Absolute Spirit) which is self-contained and not dependent on individual finite minds for its being. It aims to be the ultimate, objective account of everything.

So, What's the Big Difference? Let's Break It Down:

While both philosophers champion a mind-centric reality, they land in very different places:

1. Scope: Berkeley focuses on the relationship between individual perceivers (human and divine) and their ideas. Hegel paints on a vast canvas, describing the totality of existence (including nature and history) as a single, evolving Spirit.
2. Material World: Berkeley says poof! – no independent matter, just ideas. Hegel says matter is real but as an integral, externalized part of the Absolute Spirit's ongoing story.
3. Basis of Existence: For Berkeley, existence hinges on perception by a mind. For Hegel, existence is participation in the rational, historical unfolding of the Absolute.
4. Subjectivity vs. Absoluteness: Berkeley ties reality to subjective perception (even if God is the ultimate subject). Hegel aims for an absolute, objective account where the Spirit itself is the ultimate subject and object, encompassing all.

Final Thoughts

Comparing Berkeley and Hegel highlights the incredible diversity within idealist thought. One offers a world radically dependent on minds perceiving it, anchored by God's constant gaze. The other presents a dynamic, all-encompassing Spirit, weaving together nature, history, and consciousness into a grand, unfolding narrative of reason.

Both challenge us to reconsider the relationship between our minds and the world around us, pushing the boundaries of how we understand existence itself.

LLMs have battered my blogging!

In the old days, I would have an idea, develop it, and write it up as a post here. 

Now: I have an idea, I type it into Gemini which writes the blog post... and I don't post it here.

What value do I add when everyone has access to an LLM in 'God-mode'?

In future, what you'll get here will be either some very idiosyncratic posts indeed - thoughts not encompassed by the bland LLM summation of the collective wisdom of the world-wide web - or something very personal indeed, probably involving cats.

Here we go.

1. I am being ambushed as I get up by puss-puss. She demands I scratch her head and also rub deep inside her ears. How disgusting is that?! I have to wash my hands before I go downstairs!

2. A slightly edited blog post I asked Gemini to write for me on this topic: 

"Write a blog post of less than 650 words analysing the Vatican's dilemma with scientific research such as physics, evolutionary biology and in particular research into the Historical Jesus.

Make the point that there appear to be limits in modifying or reinterpreting Biblical scripture and theology when faced with the challenge of non-sacralised content from non-Catholic sources. How are these limits determined and are there absolute barriers?"

"The Vatican and the Tightrope Walk: Navigating Science and Scripture

The Vatican, as the center of the Catholic Church, faces a unique challenge: reconciling the ever-evolving world of scientific discovery with the timeless truths enshrined in its scriptures and theology. This tightrope walk is particularly evident in fields like physics, evolutionary biology, and even historical research on the figure of Jesus.

The Church's position on science has undergone a gradual shift throughout history. While initial reactions to revolutionary discoveries were often cautious or even hostile, the modern Church acknowledges the validity of scientific progress. Pope John Paul II, for example, famously declared that "faith and reason are like two wings on which the human spirit rises to the contemplation of truth."

However, when scientific findings seem to contradict scripture, the Church faces a dilemma. Take, for example, evolution. While accepting the reality of biological change, the Church insists on its compatibility with the doctrine of creation. This necessitates an intricate interpretation of Genesis, often drawing on allegorical readings or theological frameworks to bridge the gap.

Similarly, historical research on the life and teachings of Jesus can challenge established narratives. The discovery of non-canonical gospels, for instance, raises questions about the "true" Jesus, potentially contradicting the Gospels accepted by the Church. Reconciling these findings requires careful analysis, distinguishing between historical fact and theological interpretation.

The limits of modifying or reinterpreting scripture and theology are determined by a complex interplay of factors. Firstly, the core doctrines of the Church, like the divinity of Christ or the Trinity, are considered immutable. Secondly, the historical and literary context of scripture plays a crucial role in interpreting its meaning. Finally, the interpretations of Church authorities and theologians throughout history contribute to a cumulative understanding of faith.

However, absolute barriers are difficult to define. Science constantly evolves, and new discoveries can necessitate re-evaluations of established interpretations. Additionally, theological understanding itself is a dynamic process, with ongoing dialogue between scholars and believers. This leaves room for adaptation, but within certain boundaries.

The Vatican's approach is often characterized as cautious and deliberate. It seeks to harmonize scientific findings with scripture, finding common ground wherever possible. When contradictions seem insurmountable, it emphasizes the distinct realms of faith and reason, asserting that they ultimately lead to the same truth from different perspectives.

This balancing act is not without its critics. Some argue that the Church is too rigid, clinging to outdated interpretations in the face of scientific evidence. Others believe it compromises its core values by bending theology to accommodate secular knowledge. Ultimately, the Vatican's position reflects its unique role as a steward of both faith and reason. It strives to remain faithful to its tradition while engaging with the ever-changing world."
