Figure 6.1 Being and Becoming. The acorn and the oak allow us to frame several metaphysical questions. Are there first causes? Do things have essences? Do things develop along a predetermined path? (credit: “Acorn” by Shaun Fisher/Flickr, CC BY 2.0) Defining metaphysics is difficult. On a summary level, one possible definition is that metaphysics is the field of philosophy concerned with identifying that which is real. You may wonder why any reasonable person would invest time pursuing an answer to that which, at first glance, seems obvious. But on deeper inspection of the world around you, it can be challenging to identify what is real. Consider the acorn. As you probably learned through life science, an acorn is destined to become an oak. If you were to look at the acorn and compare it to the oak, you would see two radically different things. How can a thing change and remain the same thing? Aristotle offers insight into how the acorn and the oak represent change but within the same being. Within Aristotle’s thinking, each being has a specific end or purpose. As telos is Greek for “end” (end as target or goal), this view is known as teleological. In addition, each being is described as having a specific function (ergon) by which that being seeks the proper end. In the case of an oak tree, the oak tree works from its acorn to the fullness of the oak. Aristotle describes the becoming as movement from a state of potentiality to actuality. You might say that which is most real concerning the oak stands beneath the movement from acorn to oak. The movement from potentiality toward actuality is one method to make sense of change while maintaining a constant or underlying sense of true being. As you will discover, the topic of metaphysics is far-reaching and broaches many questions. What is real? What is being? Is there a purpose to our being? What is the self? Is there a God? Do human beings (however defined) possess free will? Metaphysical questions tend not to be resting points but starting points. This chapter begins to explore many simple yet interrelated questions as part of seeking the real. Figure 6.2 The term metaphysics comes from Aristotle’s book of the same name. The opening sentence translates as “All men by nature desire to know.” Our desire to lay bare the deepest and most discrete understanding of reality is at the heart of metaphysics.
