    Are these sentences accepted in terms of grammar?

    The sentences are as follows:
    I think, therefore I exist.
    Charles Lindbergh, for his attempt at a solo transatlantic flight, was very reluctant to have any extra weight on his plane, he therefore refused to carry even a pound of mail, despite being offered $1,000 to do so.

    I always think that "therefore" is only an adverb. Can it be possible that it is also used as a conjunction? Thanks for your help!

    ***** NOT A TEACHER *****

    Good morning, Roseriver.

    (1) I believe that most books call "therefore" either a "transitional adverb" or "conjunctive adverb."

    (a) In other words, it does the job of a conjunction + an adverb.

    (2) Mr. Lindbergh was very reluctant to have any extra weight on his plane; therefore he refused to carry even a pound of mail/ weight on his plane; he therefore refused to ....

    (a) I think most teachers require a semicolon after "plane."

    (b) "therefore" connects "he refused to carry even a pound of mail" with "Mr. Lindbergh was ... on his plane."

    (c) And as an adverb it modifies "refused."

    Thank you.

    *****

    P. S. Some people would use commas -- it's up to you. Your decision.

    on his plane; therefore, he refused. ....

    on his plane; he, therefore, refused. ....

    I think (only think) that most writers nowadays would NOT use those commas.

    The quote in Latin by Descartes "Cogito, ergo sum" is often translated in English as "I think, therefore I am". But "exist" also makes sense.
