In short
Georg Henrik von Wright (1916-2003) was Wittgenstein's student, his successor in the Cambridge chair (1948-1951) and one of his three literary executors. He edited and catalogued the Nachlass, founded deontic logic, defended understanding by reasons in Explanation and Understanding, and later shared Wittgenstein's doubts about the faith in progress.
Georg Henrik von Wright was the Finnish logician who followed Wittgenstein into the Cambridge chair and then spent half a century making his manuscripts available to the world. Born in Helsinki in 1916, he came to Cambridge in 1939, attended Wittgenstein's lectures and became a trusted friend. In 1948 he succeeded him as professor of philosophy; in 1951 he resigned and went home to Finland.
The custodian of the work
After Wittgenstein's death in 1951, von Wright became one of his three literary executors, with Elizabeth Anscombe and Rush Rhees. Much of what we now read as "Wittgenstein" exists because of them. Von Wright co-edited, among others, the Notebooks 1914-1916, Zettel and On Certainty, and edited the Vermischte Bemerkungen (1977), known in English as Culture and Value. He catalogued the whole Nachlass in "The Wittgenstein Papers" (1969), whose numbering scholars still use, and his biographical sketch of 1955 was for decades the most reliable short account of Wittgenstein's life.
What he did with it
His own work began in formal logic. In 1949, walking along the Cam, he saw that "permitted", "forbidden" and "obligatory" behave much like "possible", "impossible" and "necessary". His paper "Deontic Logic" (1951) founded a whole field, the logic of norms. Norm and Action and The Varieties of Goodness (both 1963) then asked how we really use words like "good" and "ought", in a spirit much closer to the later Wittgenstein.
His best known book, Explanation and Understanding (1971), takes up a theme Anscombe had drawn from Wittgenstein: human actions are explained by reasons and intentions, not only by causes. Von Wright reconstructed this with the practical syllogism (I want X; I believe I can only get X by doing Y; so I set myself to do Y) and defended the "understanding" of the human sciences against the idea that every explanation must follow the model of physics.
Where he differs
Von Wright never wrote like Wittgenstein. His formal calculi and tidy distinctions sit far from the later Wittgenstein's suspicion of systems, and he treated logic as a field worth building, not only as a source of confusion to be cleared away. The influence shows instead in his attention to how concepts work in life, and in his late years as a public critic of the belief in scientific and technical progress, writing in Swedish and Finnish for a wide audience. There he came closest to Wittgenstein's own unease about "the spirit of this civilisation", a phrase from a 1930 draft foreword now printed in Culture and Value. The University of Helsinki describes this path from logician to cultural critic. He was Wittgenstein's most faithful custodian, never his imitator.
Frequently asked questions
Who succeeded Wittgenstein at Cambridge?
Georg Henrik von Wright, in 1948. He resigned in 1951 and returned to Finland. Elizabeth Anscombe later held the same chair, from 1970 to 1986.
What is deontic logic?
The logic of norms: it studies how statements with "obligatory", "permitted" and "forbidden" relate to each other, for instance that what is obligatory must also be permitted. Von Wright's 1951 paper is usually taken as its starting point.
