But at its core lies a paradox--it is unmeasurable. This book presents a powerful and energetic new approach to the measurement dilemma.

With this third edition of Nelson Goodman's The Structure of Appear- ance, we are pleased to make available once more one of the most in- fluential and important works in the philosophy of our times. Professor Geoffrey Hellman's introduction gives a sustained analysis and appreciation of the major themes and the thrust of the book, as well as an account of the ways in which many of Goodman's problems and projects have been picked up and developed by others. Hellman also suggests how The Structure of Appearance introduces issues which Goodman later continues in his essays and in the Languages...
