Alan Turing
Defined computation, advanced logic and codebreaking, and framed the modern question of machine intelligence.

Life and thought
Investigates computation, intelligence, logic, codebreaking, algorithms, and the boundaries of machine thought.
Alan Turing is presented in the Thought archive through mathematics, british, britain, modern. The recorded life dates are 1912–1954. The profile connects this work to Computing, Logic, Mathematics, Science.
The central questions gathered here concern Turing machine, computation, imitation game, algorithms, cryptanalysis. Together they show the recurring problems, methods, and distinctions that define this thinker’s contribution.
Alan Turing developed within an intellectual conversation shaped by Gödel, Hilbert, Church, mathematical logic. These names provide context for the traditions and problems surrounding the work; they do not imply simple agreement.
The surviving reading path begins with On Computable Numbers, Computing Machinery and Intelligence, Systems of Logic. The recorded legacy extends toward computer science, AI, cryptography, philosophy of mind.

We can only see a short distance ahead.
Sometimes it is the people no one imagines anything of who do things.
Machines take me by surprise with great frequency.
A computer would deserve to be called intelligent if it could deceive a human.
Mathematical reasoning may be regarded rather schematically.
