Preface to Part II Ernest’s Reflecti<strong>on</strong>s<br />

<strong>on</strong> <strong>Theories</strong> <strong>of</strong> Learning<br />

Lakatos-Hersh-Ernest: Triangulating<br />

Philosophy-<strong>Mathematics</strong>-<strong>Mathematics</strong> Educati<strong>on</strong><br />

Bharath Sriraman and Nick Haverhals<br />

Philosophy has always maintained an intricate relati<strong>on</strong>ship with mathematics. It was<br />

also implicitly accepted that the philosophical positi<strong>on</strong>s <strong>of</strong> a bearer influence his/her<br />

view <strong>on</strong> mathematics and its teaching (Törner and Sriraman 2007), which leads us<br />

into the domain <strong>of</strong> beliefs theory. However the centrality <strong>of</strong> philosophy and its intricate<br />

relati<strong>on</strong>ship to theory development in mathematics educati<strong>on</strong> <strong>on</strong>ly came about<br />

two decades ago when Paul Ernest and Hans-Georg Steiner (1987) each independently<br />

became aware <strong>of</strong> the importance <strong>of</strong> epistemological issues that impact the<br />

teaching and learning <strong>of</strong> mathematics. Sierpinska and Lerman (1996) state:<br />

Epistemology as a branch <strong>of</strong> philosophy c<strong>on</strong>cerned with scientific knowledge poses fundamental<br />

questi<strong>on</strong>s such as: ‘What are the origins <strong>of</strong> scientific knowledge?’ (Empirical?<br />

Rati<strong>on</strong>al?); ‘What are the criteria <strong>of</strong> validity <strong>of</strong> scientific knowledge?’ (Able to predict actual<br />

events? Logical c<strong>on</strong>sistency?); ‘What is the character <strong>of</strong> the process <strong>of</strong> development <strong>of</strong><br />

scientific knowledge?’ (Accumulati<strong>on</strong> and c<strong>on</strong>tinuity? Periods <strong>of</strong> normal science, scientific<br />

revoluti<strong>on</strong>s and disc<strong>on</strong>tinuity? Shifts and refinement in scientific programs?).<br />

The questi<strong>on</strong> <strong>of</strong> what is mathematics, for teaching and learning c<strong>on</strong>siderati<strong>on</strong>s<br />

brings into relevance the need to develop a philosophy <strong>of</strong> mathematics compatible<br />

with mathematics educati<strong>on</strong>. In order to answer this questi<strong>on</strong> for mathematics<br />

educati<strong>on</strong>, several theorists have played a role directly or indirectly. In this preface,<br />

we briefly summarize the role that Lakatos, Hersh and Ernest have played. Reuben<br />

Hersh began to popularize Lakatos’ book Pro<strong>of</strong>s and Refutati<strong>on</strong>s to the mathematics<br />

community in a paper titled, “Introducing Imre Lakatos” (1978) and called for the<br />

community <strong>of</strong> mathematicians to take an interest in re-examining the philosophy <strong>of</strong><br />

mathematics. Hersh (1979) defined the “philosophy <strong>of</strong> mathematics” as the working<br />

philosophy <strong>of</strong> the pr<strong>of</strong>essi<strong>on</strong>al mathematician, the philosophical attitude to his work<br />

that is assumed by the researcher, teacher, or user <strong>of</strong> mathematics and especially the<br />
