By exploring other worlds we safeguard this one. By itself, I think this fact more than justifies the money our species has spent in sending ships to other worlds. It is our fate to live during one of the most perilous and, at the same time, one of the most hopeful chapters in human history.
If you ever go behind the glass and look at the focus groups that are deciding what you're gonna watch, it's scary. This cross-section of people they just happen to bring in to decide the fate of mankind on television is really scary.
[M]ore than they wanted freedom, the Athenians wanted security. Yet they lost everything-security, comfort, and freedom. This was because they wanted not to give to society, but for society to give to them. The freedom they were seeking was freedom from responsibility. It is no wonder, then, that they ceased to be free. In the modern world, we should recall the Athenians' dire fate whenever we confront demands for increased state paternalism.
Our situation on this earth seems strange. Every one of us appears here involuntarily and uninvited for a short stay, without knowing the whys and the wherefore. In our daily lives we only feel that man is here for the sake of others, for those whom we love and for many other beings whose fate is connected with our own. I am often worried at the thought that my life is based to such a large extent on the work of my fellow human beings and I am aware of my great indebtedness to them.
Humanity is our common lot. All men are made of the same clay. There is no difference, at least here on Earth, in the fate assigned to us. We come of the same void, inhabit the same flesh, are dissolved in the same ashes. But ignorance infecting the human substance turns it black, and that incurable blackness, gaining possession of the soul, becomes Evil.
