What is it that we can hold fast and know for sure? So much changes. Earth isn’t flat and isn’t the center of the universe although generations came and went believing that to be true. Gravity kept the planets in orbit and people from floating off long before anyone noticed and named it. Atoms existed before anyone discovered they could be split.

What is it that may be discovered in the future that can make sense of the way we act and feel now? Is there a key to explaining human behavior? A force, perhaps, that pulls people apart despite a deep desire to connect? What if there is another sense more important than the five we rely on now?

One thing good about change is it keeps you humble. Or should. Knowing that what we know is a minuscule speck in the ocean of all that can be known helps us stay open and curious. Where would the adventure be if we ever knew it all anyway?
