Objective Truth

The question "What is truth?" seems to be falling from the lips of virtually everyone these days. Like Pilate circa 30CE, the philosophical often look at it as a question of personal viewpoint. What is true for me may not be true for you.
There is a problem with this logic, though. There really is objective truth. The sky has a blue appearance even though the colorblind cannot distinguish it. A tennis ball is spherical even though the toddler holding it does not know the name of the shape. Some things are objectively true. Children learn to distinguish fantasy from reality when we teach them to observe with their senses what is concrete and what is mere trickery.
Why is it important for us, as people, to distinguish what is true and what is false? For starters, we need to know our limitations in order to understand our capabilities. A basic understanding of gravity prevents us from stepping off a balcony twelve floors up. The understanding that fire produces much heat prevents us from putting our hand into the flame on the stove.
Likewise, understanding objective truths about who we are helps us to attend to our mental and spiritual needs. If we attempt to live as if the truth doesn't matter, we are bound to be disappointed eventually. No matter how hard we try to make everyone be nice and bear with a person's personal beliefs about themselves, eventually someone will state what is painfully obvious and tear down the mental castle of sand that is self-delusion.
Let us always be truthful when dealing with others, but let us also always deal with the truth in love.
