ABSTRACT
In this chapter, we explore two of the most controversial writings of Popper and Hayek, produced in 1934-1935: The Logic of Scientific Discovery (hereafter LSD) and Collectivist Economic Planning (hereafter CEP). I begin by explaining the significance of the title by exploring its presuppositions and then make some key distinctions. Next, I summarize several key theses in LSD and then summarize the major arguments in CEP. One difference between the two books is that CEP is an edited collection while LSD is a single-author work. This chapter will include discussions of two important papers by Hayek on knowledge and the ECA written in 1937 and 1945 that supplement his argument in CEP (both are reprinted in Individualism and Economic Order, hereafter IEO).
