The list of readings will use the abbreviations below. References are typically by sections rather than by pages, but there are exceptions; see below.

• TLP: Tractatus Logico-Philosophicus
• PI: Philosophical Investigations; references in Part I by section number (for example, PI 158 refers to the Philosophical Investigations, section 158), references in Part II by page number (e.g., PI p. 150). (N.B.: pagination has changed between the 3rd -- formerly standard -- edition and the current edition; I'll be giving the pagination in the current edition.)
• NB: Notebooks 1914-1916; references by page number and entry date.
• PR: Philosophical Remarks
• OC: On Certainty
• BB: The Blue and Brown Books
• RFM: Remarks on the Foundations of Mathematics; references by part and section number (e.g., I-149 means Part I, section 149).
