What’s in it for me? A journey to the limits of language.

Can philosophy provide insight into life’s biggest questions? What are the limits of language to express it? Are metaphysics and ethics just nonsensical babble? In his cryptic masterpiece Tractatus Logico-Philosophicus, Ludwig Wittgenstein confronts these problems head-on. He aims to establish the boundaries of meaningful language – to separate sense from nonsense – in philosophy.

Wittgenstein argues that most traditional philosophical questions are actually just misuses of language. They try to say what can’t be meaningfully said. His linguistic atomism claims language can only picture concrete facts about the world. Anything beyond that is meaningless. This includes ethics, aesthetics, metaphysics, and religion. For Wittgenstein, these aren’t factual topics, so we can’t meaningfully discuss them.

Tractatus attempts to scrub away the nonsense plaguing philosophy. Its radical claim is that our biggest questions about meaning and value have no answers. We simply can’t discuss them. This controversial view shaped twentieth-century philosophy. Love it or hate it, Tractatus will make you think about how you think.

At the boundary of the world

A central theme in Wittgenstein's Tractatus Logico-Philosophicus is that language demarcates the frontiers of meaning. As Wittgenstein famously states, “The limits of my language are the limits of my world.” In other words, whatever can be expressed in words constructs the boundaries of our knowable reality.

He argues that we can't meaningfully discuss anything beyond language's pictorial nature. Language can only portray hard facts and logical interconnections. It can't capture subtle metaphysical truths, ethical imperatives, or subjective aesthetics.

Since language is tethered to facts, whatever escapes words also lies outside the limits of our experiential world. The indescribable essence of life – how one should live, why we exist, the nature of consciousness – can't be conveyed through literal language. Wittgenstein observes that “There are indeed things beyond words, which make themselves known. These are mystical.”

Profound mystical experiences may feel rich with significance, yet the moment we try to put them into words we leave behind the realm of sense for nonsense. In Wittgenstein's iconic phrase, “What can be shown cannot be said,” the unsayable truths underlying existence reveal the frontier between language and lived reality.

So anything exceeding language's descriptive powers falls outside knowable reality. Language, Wittgenstein posits, comprises all we possess to construct meaning from reality – he says, “The thinking self is not IN the world, but is a boundary OF the world.” We can't talk meaningfully from outside our language-constructed world.

Wittgenstein's original insight on language's limits revolutionized philosophy. He exposed how traditional philosophy vainly tried to verbalize the ineffable. Fields like ethics, metaphysics, and theology transgressed the frontiers of sense. This compelled philosophy to demarcate what we can discuss versus what we must be silent about. Our world stretches only as far as we can meaningfully describe in words. The remainder persists as an unfathomable mystery, glimpsed but never grasped.

What can I say?

A key goal of Tractatus is to use logic and philosophy to determine what can be meaningfully said. Wittgenstein states that philosophy's purpose is the logical clarification of thoughts. It seeks to delineate sense from nonsense through rigorous logical analysis.

He argues that traditional philosophy fails this task by trying to express the inexpressible, lapsing into nonsensical language. In his view, most philosophical questions and propositions aren't even false, but simply nonsensical. Fields like metaphysics, ethics, and theology claim to provide factual knowledge when what they really generate is nonsense. He points out that the sheer fact of existence itself can't be communicated meaningfully in language.

Math isn’t real

One of Wittgenstein's most thought-provoking arguments is that mathematical equations don't describe real things. In other words, mathematical propositions don’t express factual thoughts about the world.

Like ordinary language, he contends that mathematical propositions contain tautologies – or vacuous statements showcasing the internal relations between concepts rather than concrete realities. He explains that the logic displayed in logical tautologies is analogously shown in mathematical equations. Mathematics can only express itself logically, which is why it appears perfectly orderly yet detached from substance.

The mystical self

Perhaps the most enigmatic argument in Tractatus is that solipsism – the view that only the self exists while the external world is an illusion – grasps at something true but can't be meaningfully articulated.

Wittgenstein contends that solipsism wrongly attempts to logically portray the relationship between self and world. He states that the spirit of what the solipsist means is correct, but it can't be directly said – rather, it shows itself. We can't definitively prove through logic the independent existence of the world and other minds. Yet language itself implies their reality. In his view, a shared language points to a shared world.

The myth of meaning

Do virtuous actions really lead to positive outcomes? Is there some universal justice ensuring wrongs are eventually made right? Wittgenstein's philosophy implies concepts like karmic retribution are merely wishful thinking. His critique of causality suggests notions of cosmic payback and “what goes around comes around” are comforting fictions, not actual metaphysical truths.

In fact, he argues that ideas like cause and effect don't really link events in reality. We observe regular successions and patterns of facts, but can't definitively know the underlying causes behind them. Causality is a projection of the mind onto the world, not something inherent in the fabric of reality itself. It’s a useful tool for describing empirical patterns, not an actual force governing affairs.

To show and not tell

One of the more thought-provoking ideas in Tractatus is that language as a symbol system can't logically define or fully capture particular colors or subjective color experiences. Wittgenstein argued that colors aren't concrete objects that propositions can accurately describe or encapsulate solely through words. We can't pin down the essence of color sensations strictly through linguistic means.

While it may initially seem like an obscure point, Wittgenstein used the color exclusion problem to underscore a major gap between reality as subjectively lived through consciousness, and language's limited capacity to communicate that experience.

Ich bin begeistert. Ich liebe Bücher aber durch zwei kleine Kinder komme ich einfach nicht zum Lesen. Und ja, viele Bücher haben viel bla bla und die Quintessenz ist eigentlich ein Bruchteil.

Genau dafür ist Blinkist total genial! Es wird auf das Wesentliche reduziert, die Blinks sind gut verständlich, gut zusammengefasst und auch hörbar! Das ist super. 80 Euro für ein ganzes Jahr klingt viel, aber dafür unbegrenzt Zugriff auf 3000 Bücher. Und dieses Wissen und die Zeitersparnis ist unbezahlbar.

Extrem empfehlenswert. Statt sinnlos im Facebook zu scrollen höre ich jetzt täglich zwischen 3-4 "Bücher". Bei manchen wird schnelle klar, dass der Kauf unnötig ist, da schon das wichtigste zusammen gefasst wurde..bei anderen macht es Lust doch das Buch selbständig zu lesen. Wirklich toll

Viele tolle Bücher, auf deren Kernaussagen reduziert- präzise und ansprechend zusammengefasst. Endlich habe ich das Gefühl, Zeit für Bücher zu finden, für die ich sonst keine Zeit habe.
