Early Wittgenstein & logical positivism
“In order to determine the sense of a proposition, I should have to know a very specific procedure for when to count the proposition has been verified”.
Wittgenstein and the Vienna Circle, p.47

Picture theory of meaning
“A propositional sign is a fact...In a
proposition a name is the representative
of an object”
(Tractatus 3.14; 3.22)

Tractatus and science
Verifiability as:- Demarcation criterion- Meaning criterion
Metaphysics becomes nonsense
Science proceeds by induction
![Page 9: Popper and the Poker - Barnes Philosophy Society](https://reader034.fdocuments.us/reader034/viewer/2022051111/556357d1d8b42a6f7b8b5865/html5/thumbnails/9.jpg)
The problem of (with) induction
The supposition that the future resembles the past, is not founded on arguments of any kind, but is derived entirely from habit.
(David Hume, 1737)
![Page 10: Popper and the Poker - Barnes Philosophy Society](https://reader034.fdocuments.us/reader034/viewer/2022051111/556357d1d8b42a6f7b8b5865/html5/thumbnails/10.jpg)
How does Popper avoid induction?•Theories are never verified: they remain
conjectures•They have the form of universal
statements: “wherever A, then B” given right initial conditions
•No number of A & B can prove; one A & not-B can falsify: an asymmetry
![Page 11: Popper and the Poker - Barnes Philosophy Society](https://reader034.fdocuments.us/reader034/viewer/2022051111/556357d1d8b42a6f7b8b5865/html5/thumbnails/11.jpg)
Falsification and demarcation
GeminiYou may be feeling a bit reserved today…Promising new projects may present themselves.

Falsification isn’t simple/binary
•Ad hoc hypotheses
•Artificial theories & preference

Popper’s Hegel-bashing
“his philosophical arguments are not to be taken seriously... A major factor in bringing about the ‘age of intellectual dishonesty’...contributed to the rise of totalitarian philosophising”
