“A paradox is a statement that apparently contradicts itself and yet might be true. Most logical paradoxes are known to be invalid arguments but are still valuable in promoting critical thinking.
Some paradoxes have revealed errors in definitions assumed to be rigorous, and have caused axioms of mathematics and logic to be re-examined. One example isRussell’s paradox, which questions whether a “list of all lists that do not contain themselves” would include itself, and showed that attempts to found set theory on the identification of sets with properties or predicates were flawed. Others, such as Curry’s paradox, are not yet resolved.
Examples outside logic include the Ship of Theseus from philosophy (questioning whether a ship repaired over time by replacing each of its wooden parts would remain the same ship). Paradoxes can also take the form of images or other media. For example, M.C. Escher featured perspective-based paradoxes in many of his drawings, with walls that are regarded as floors from other points of view, and staircases that appear to climb endlessly.
Students will use Google or Bing or Yahoo! to find two images: 1. a background that you choose to be in direct conflict with the reality of the 2. object (or subject) in it. Open your background in Photoshop, then choose File-Place and place your object or thing into the composition. You may grab the bounding box by the handles and re-size it as you wish, then choose Enter to accept the Placement (or hit Escape to reject it).
Use the Eraser Tool (E) to remove the background. Use the Move Tool (V) while holding down the Alt key on the keyboard to drag a copy of the object or item. Once you have a copy of the object, then choose Image-Free Transform (or Control + T) to re-size the new copy as you wish. Use the Move Tool and the Alt key to copy the object over and over, then Free Transforming it over and over with Control + T or Image-Free Transform!
