A self-imposed exile
Wittgenstein's early work was consumed with the dream of a perfect language – one where words mapped precisely onto the world's underlying logical structure. He believed that for language to possess clear and determinate sense, it had to mirror reality itself via strict definitions and propositions. Like a model train track connecting objects to their exact symbolic counterparts. Only this way, Wittgenstein thought, could philosophy resolve its enduring problems and ambiguities. By creating an ideal formal system where each word equates to one immutable thing.
The result of this rigorous thinking was his first publication, written and edited while the philosopher served in the Austro-Hungarian army during the First World War. But as scholars of philosophy well know, Wittgenstein’s academic path took an unconventionally unique route. His groundbreaking Tractatus Logico-Philosophicus began as his doctoral dissertation, submitted to Cambridge University in 1918, after earlier conceptual work beginning in 1913. This prodigious beginning seemed poised to launch a storied academic career.
Curiously, Wittgenstein concluded at this young age that his philosophical questions were essentially resolved in the Tractatus. So rather than enjoying accolades within academia’s cozy halls, he left – choosing instead to work humbly as a gardener, learning carpentry and training as an elementary teacher. For almost five years Wittgenstein disappeared from professional philosophy, inhabiting rural life and manual labor.
This unique period of exile seems, in retrospect, to have been profoundly formative. While not resulting in further publications until after his death in 1951, the insights Wittgenstein eventually penned in his enduring Philosophical Investigations clearly reflect this renewed perspective. Its quintessentially contemporary themes stand as a foundation for language philosophy as we know it today.
For Wittgenstein, his time digging ditches, enjoying popular films, and reading detective novels opened a window to ordinary language's overlooked richness. The myriad hues of casual chatter, patterns of humor, and lyrics from popular songs kindled a new recognition: words gain meaning through fluid use in varied contexts, not through a fixed, logical form.
So, Wittgenstein relinquishes the notion of language as some singular immutable system. Instead, he realizes it functions more as a motley accumulation of what he calls language games – and embraces the pluralism of vernacular speech. He sees language interweaving fluidly with action, allowing new meanings and forms to evolve. Sense can emerge from apparent nonsense, truth from lies, or clarity from contradiction.
This seismic shift overturned the logical atomism dominating the philosopher’s age. Out went the notion of a single underlying structure giving language its meaning. In came multiplicity and changeability – no more tight mapping between words and world required. Now, language gains sense by pragmatic use across contexts, the way a tool finds its purpose through practices. Games beget games, meanings beget meanings.
Thus in one daring move, Wittgenstein invented contemporary philosophy – founding it on language's dynamic, formative nature. Philosophical problems often arise from assuming words possess some fixed essence when meaning evolves contextually instead.
