Frege, Sentence-questions, Questions, and Thoughts

Abstract Dummett, Hanks, Künne, and Bobzien have all stated or implied that when Frege wrote ‘Über Sinn und Bedeutung’, Frege believed that the sense of a sentence-question was not a thought. I present the passage of ‘Über Sinn und Bedeutung’ which is relevant to the evaluation of that proposition. I then present and evaluate an argument which I assume to be the best argument based on that passage for that proposition. I argue that the argument is likely to be unsound. I also address the question whether Frege believed that sentence-questions could be true or false and discuss what Frege did say and what he should have said about logical-alternative questions.
