Abstract: 
In this talk, we review briefly the situation which led to the acceptance of scalar interactions on top of the gauge ones, and argue they are the only feeble interaction. We use the P and CP concepts to discuss to which extent they might be composite or possibly originate from extra dimensions, and mention a situation where the latter possibility may reduce the number of couplings.
