This book examines 13th century views about time, particularly the views of Thomas Aquinas and his contemporaries in the middle of the century. As medieval thinkers considered time to be just another duration alongside the durations of aeviternity (the aevum) and eternity, the scope of the study covers all three durations, culminating in an examination of God’s relationship to time. Chapter 1 opens the discussion by examining some of the key language and terminology which 13th century thinkers used. Chapters 2-5 (...) examine the topological properties of time: the properties that determine its shape and structure. Chapter 6 investigates the metrical properties of time: the properties pertaining to time when it is considered as a measure. Chapter 7 looks at the criteria, factors, and language which 13th century thinkers typically took as entailing that a particular would be in time. Chapter 8 explores how 13th century thinkers discussed existence outside of time, particularly as it was applied to aeviternity and aeviternal beings. Chapter 9 examines the content of the medieval concept of eternity, and how these ideas are best rendered in contemporary language. Chapter 10 examines the specific question of how 13th century thinkers viewed God’s relationship to time. (shrink)
