Individual Choice Sequences in the Work of L.E.J.Brouwer Joop Niekus Abstract: Choice sequences are sequences not completely determined by a law. We state that the introduction of particular choice sequences by Brouwer in the late twenties was not recognised as such. We claim that their later use in the method of the creative subject was not traced back to this original use of them and has been misinterpreted. We show where these particular choice sequences appear in the work of Brouwer and we show how they should be handled. Keywords: Intuitionism, choice sequences, the method of the creative subject.
