Introduction: Why Learning Logic Is like Learning to Swim . . . (you must read the Introduction!)

Logic Self-Taught is addressed to anyone who answers at least one of the following questions positively:

¨ Do you like puzzles (logical puzzles, crossword puzzles etc.)?

¨ Have you ever felt that you understood everything in a logic class or in a logic textbook but you were completely helpless in a logic test?

¨ Do you have more of a hate- than a love-relationship with mathematical symbols?
