Were we created for this purpose?
Were we given eyes to behold the beauty of this world?
Do we have noses to enjoy the scents of flowers?
Were our tongues and throats constructed so that we could sing?
Were we granted brains so we might dream of fantastic worlds?
Are we smaller or lesser if the answer is no?
We see because sight means recognition of threats, of landmarks, of faces, whether friend, family or foe.
We smell because smell warns us of disease and decay, and invites us to eat what is safe and nutritious.
We have speech because speech means the development of language, which is the gateway to a culture of communication, understanding, and history.
And our brains became remarkable only through millions of years of development. We were not always as we are.
Our brains make us capable of learning and teaching. We are animals; but our brains make us remembering animals. They make us social animals. They make us creative animals. Brains began as some vague cluster of something like neurons, able to do nothing more complex than add one and one. Through some fabulous course of evolution, we have now the human brain: a strange, slimy lump of meat inside of our skulls that gives us the power to love one another.
Understanding the cause does not diminish the effect.
