ABSTRACT
In the "Outline Classification of the Sciences", the first chapter of the Syllabus, Charles S. Peirce had defined phenomenology as the science of the "kinds of elements universally present in the phenomenon; meaning by the phenomenon, whatever is present at any time to the mind in any way". In "Sundry Logical Conceptions" (SLC), speculative grammar is preceded by an exposition of the phenomenological categories and of the principles of the normative sciences of esthetics and ethics, that is, of the philosophical sciences that precede logic in Peirce's classification of the sciences. While retained in the final version of SLC, the distinction between primary and secondary object will never be employed again in Peirce's taxonomic investigations. The difference between the first draft of the Syllabus's chapter on grammar and the second and final draft thereof is also reflected in the draft materials for the Lowell Lectures, whose plan underwent significant changes and re-scheduling both in their preparation and in their delivery.
