Thought Experiment

  • Julie and Mark and brother and sister
  • They try and experiment and make love, and take birth control pills
  • Is what they have done wrong?

Responses

Wrong

  • The chance of becoming pregnant is non-zero, bringing up a new child is messed up
  • Incest is usually tied to abuse
  • Family dynamics will be permanently affected, which is wrong
  • Mentally wrong, Julie will be endorsing this behavior for her children too
  • Sex with the intent for pleasure is wrong

Not Wrong

  • It is not wrong, just weird
  • It is not causing anyone harm, there is also no abuse in this case
  • The only issue with incest is bringing about a child with genetic defects

Argument For Wrong

It is wrong because:

P1: Mark and Julie and Brother and Sister
P2: If Mark and Julie have sex, then Julie could get pregnant
P3: If she gets pregnant, then the child will likely have a serious disability
P4: It is wrong to create a child with a serious disability
C: Therefore, it is wrong for Julie and Mark to have sex
