Text is the most complex object in linguistics. Coseriu's integral linguistics is a key to text analysis. The transversality of the approach, also integrating the reality of the world, echoes several 20th century theories such as enunciation (E. Benveniste), functionalism (M.A.K. Halliday), convention philosophy of language (L. Wittgenstein). We propose to add process philosophy (A. Whitehead) - indeed, our research in text linguistics focuses on the study of textualization processes which are real-time recorded by key-stroke logging software. The nature of the data segmented by pauses during the writing process, the temporal linearity oriented towards the final product, the hypothesis of a preexisting textual design can be satisfactorily examined in the frame of integral linguistics, and also contribute new developments.
