Der Tod ist kein Ereignis des Lebens. Den Tod erlebt man nicht. Wenn man unter Ewigkeit nicht unendliche Zeitdauer, sondern Unzeitlichkeit versteht, dann lebt der ewig, der in der Gegenwart lebt. Unser Leben ist ebenso endlos, wie unser Gesichtsfeld grenzenlos ist.
1920s, Tractatus Logico-Philosophicus (1922)
Variante: Death is not an event of life. Death is not lived through.
If by eternity is understood not endless temporal duration but timelessness, then he lives eternally who lives in the present.
Our life is endless in the way that our visual field is without limit.

As quoted in "A View from the Asylum" in Philosophical Investigations from the Sanctity of the Press (2004), by Henry Dribble, p. 87

On Certainty (1969)

Journal entry (8 July 1916), p. 74e
1910s, Notebooks 1914-1916
Contexte: There are two godheads: the world and my independent I.
I am either happy or unhappy, that is all. It can be said: good or evil do not exist.
A man who is happy must have no fear. Not even in the face of death.
Only a man who lives not in time but in the present is happy.

Original German: Ein Satz kann unmöglich von sich selbst aussagen, dass er wahr ist.
1920s, Tractatus Logico-Philosophicus (1922)

Journal entries (12 March 1915 and 15 March 1915) p. 41e
1910s, Notebooks 1914-1916
Contexte: I cannot get from the nature of the proposition to the individual logical operations!!!
That is, I cannot bring out how far the proposition is the picture of the situation. I am almost inclined to give up all my efforts.

Original German:Die Logik erfüllt die Welt; die Grenzen der Welt sind auch ihre Grenzen. Wir können also in der Logik nicht sagen: Das und das gibt es in der Welt, jenes nicht.Das würde nämlich scheinbar voraussetzen, dass wir gewisse Möglichkeiten ausschließen, und dies kann nicht der Fall sein, da sonst die Logik über die Grenzen der Welt hinaus müsste; wenn sie nämlich diese Grenzen auch von der anderen Seite betrachten könnte. Was wir nicht denken können, das können wir nicht denken; wir können also auch nicht sagen, was wir nicht denken können.
1920s, Tractatus Logico-Philosophicus (1922)
Contexte: Logic pervades the world: the limits of the world are also its limits. So we cannot say in logic, "The world has this in it, and this, but not that." For that would appear to presuppose that we were excluding certain possibilities, and this cannot be the case, since it would require that logic should go beyond the limits of the world; for only in that way could it view those limits from the other side as well. We cannot think what we cannot think; so what we cannot think we cannot say either. (5.61)

Journal entry (11 June 1916), p. 72e and 73e
1910s, Notebooks 1914-1916
Contexte: What do I know about God and the purpose of life?
I know that this world exists.
That I am placed in it like my eye in its visual field.
That something about it is problematic, which we call its meaning.
This meaning does not lie in it but outside of it.
That life is the world.
That my will penetrates the world.
That my will is good or evil.
Therefore that good and evil are somehow connected with the meaning of the world.
The meaning of life, i. e. the meaning of the world, we can call God.
And connect with this the comparison of God to a father.
To pray is to think about the meaning of life.

He must so to speak throw away the ladder, after he has climbed up on it.

Original German: Meine Sätze erläutern dadurch, dass sie der, welcher mich versteht, am Ende als unsinnig erkennt, wenn er durch sie—auf ihnen—über sie hinausgestiegen ist. (Er muss sozusagen die Leiter wegwerfen, nachdem er auf ihr hinaufgestiegen ist.)
1920s, Tractatus Logico-Philosophicus (1922)

Variant translation: Philosophy is not a theory but an activity. A philosophical work consists essentially of elucidations. The result of philosophy is not a number of "philosophical propositions." but to make propositions clear.
Original German: Der Zweck der Philosophie ist die logische Klärung der Gedanken. Die Philosophie ist keine Lehre, sondern eine Tätigkeit. Ein philosophisches Werk besteht wesentlich aus Erläuterungen. Das Resultat der Philosophie sind nicht „philosophische Sätze“, sondern das Klarwerden von Sätzen. Die Philosophie soll die Gedanken, die sonst, gleichsam, trübe und verschwommen sind, klar machen und scharf abgrenzen.
1920s, Tractatus Logico-Philosophicus (1922)
Contexte: Philosophy aims at the logical clarification of thoughts. Philosophy is not a body of doctrine but an activity. A philosophical work consists essentially of elucidations. Philosophy does not result in 'philosophical propositions', but rather in the clarification of propositions. Without philosophy thoughts are, as it were, cloudy and indistinct: its task is to make them clear and to give them sharp boundaries. (4.112)

Certain, possible, impossible: here we have the first indication of the scale that we need in the theory of probability.
