We do not treat others well simply because of a religious book say to or because our parents raised us to. Empathy, the ability to put yourself into another's shoes, is an innate human ability. It is an ability that can and needs to be improved and focused on.
Science would not include emotion in this list, but we are not all scientists. Emotion is part of our world. Sometimes this is good, sometimes bad, but emotion is integral to humanity. Having our minds made up for us by others citing only works of blind faith is always bad.
Why: To whom much has been given much is expected. It makes sense to help as many as possible to enjoy life which in the end is also in one’s self interest. And it is for the common good which we need to survive.
Why: A truly secular state permits real religious freedom because no one group has a monopoly on the truth. Science continually makes new discoveries and revelations No one has a corner on truth or faith issues.
A lifelong appreciation for science and art fosters a wonder in the world. Continuing to question what you believe through science and expressing yourself through art creates an ideal venue to maximize the intellectual and emotional growth of a person.
Pain and suffering are, for the foreseeable future, part of life. However, we have the ability to minimize suffering . I believe we have a moral imperative to use our knowledge to minimize suffering for all people and but also research animals and animals we use for food.
The modern recognition of the value and autonomy of the human individual has unfortunately obscured the obligation that the individual still has to others. For it is still in each other -- together -- that we find happiness, meaning, and security, if we find them at all.
We are so divided and negative towards each other. We see each other as obstacles - as a another opinion to be eradicated. Sometimes, just accepting the differences in others, will cause them to show you the same respect.
Humans are among the most versatile creatures on this planet due to our reasoning capabilities. These should not be hindered, but encouraged. Humanity can rise to the stars and beyond if we unite for the accumulation of knowledge.
When I re-think of how religious dogma has held back human progress, not only in physics, but also in our humanistic view of the world, I submit that freedom of thought is vital to human progress.
