Taste

Opposition in all things—knowing the good that He may shun the evil… There is never a reason to know what bad tastes like, because if you only know the good, you will immediately and instantly know that anything that tastes bad, is not good!

We know the bitter to prize the good but also, as the late Elder Neal A. Maxwell said, "We set our own thermostat as to temptations".

So, in one sense, we can manipulate our senses. There actually is a Good, like following God's commandments or doing His will.
