Moreover, until Russell and Whitehead’s Principia Mathematica 3 vols. Thoughts are expressed by propositional questions which are not assertoric as well as interrogative sentences which are assertoricindicating that the assertion of a Thought is a separate issue from its truth value e.

Take care that nothing gets lost.

Names such as “Romulus” or “Odysseus”, and phrases such as “the least rapidly converging series” or “the present King of France” express senses, insofar as they lay out criteria that things would have to satisfy if they were to be the references of these expressions.

The Begriffsschrift broke new ground, including a rigorous treatment of the ideas of functions and variables.
