Collection 1.1

If-Then Reasoning

If-then statements have a direction. Notice how the arrow only points one way? With how we use language, that's not always clear as day.

What to Notice

  • That feeling of something being off, melting away
  • A growing recognition of arguments that sound airtight until we look closer
  • The quiet satisfaction of seeing exactly how a claim connects to its support
  • A growing sense for when conclusions outrun their reasons
