Brzozowski's "philosophy of labour'—to which he devoted a number of writings starting in 1902—presents problems of interpretation. A conceptual approach to his conception shows it to be a sometimes uneasy mix of realist and anti-realist notions. Brzozowski appears to have thought that labour is not first of all about the things it supposedly transforms, but rather about itself. I suggest that Brzozowski can be read in the spirit of Nelson Goodman's nominalist constructionalism ("worldmaking"). On this account, labour in Brzozowski's idiom turns out to be the constitution of forms of symbolizing sufficient unto themselves and the needs they satisfy. However, that Brzozowski was not entirely consistent in the views I impute to him—he forever sought for some "external' measure of the rightness of labour/symbolizing—can be explained at least in part by his "humanism', that is, his commitment to the task he assigns humankind, that of creating the one meaningful world attesting to virtually unrestricted human power.
