—  William Kingdon Clifford English mathematician and philosopher 1845 - 1879

The Ethics of Belief (1877), The Limits Of Inference
Kontext: p>We may believe what goes beyond our experience, only when it is inferred from that experience by the assumption that what we do not know is like what we know. We may believe the statement of another person, when there is reasonable ground for supposing that he knows the matter of which he speaks, and that he is speaking the truth so far as he knows it.It is wrong in all cases to believe on insufficient evidence; and where it is presumption to doubt and to investigate, there it is worse than presumption to believe.</p

„Knowing Yourself …We also seldom know what gifts we are not endowed with. We will have to learn where we belong, what we have to learn to get the full benefit from our strengths, where our weaknesses lie, what our values are. We also have to know ourselves temperamentally: "Do I work well with people, or am I a loner? What am I committed to? And what is my contribution?"“

„I know not what fear is, nor I know not what it is that I fear now; I fear not the hastening of my death, and yet I do fear the increase of the disease… my weakness is from nature, who hath but her measure, my strength is from God, who possesses and distributes infinitely.“

Varianta: Risk comes from not knowing what you’re doing.

„And when such behavior emanates from the top of our government, it is something else. It is dangerous to a democracy. Such behavior does not project strength because our strength comes from our values. It instead projects a corruption of the spirit and weakness. It is often said that children are watching. Well, they are. And what are we going to do about that? When the next generation asks us, ‘Why didn’t you do something? Why didn’t you speak up?’ What are we going to say?“

„A strong defense is the surest way to peace. Strength makes détente attainable. Weakness invites war, as my generation—my generation—knows from four very bitter experiences.“

—  Gerald Ford American politician, 38th President of the United States (in office from 1974 to 1977) 1913 - 2006

1970s, Address to Congress (12 August 1974)
Kontext: A strong defense is the surest way to peace. Strength makes détente attainable. Weakness invites war, as my generation—my generation—knows from four very bitter experiences. Just as America's will for peace is second to none, so will America's strength be second to none. We cannot rely on the forbearance of others to protect this Nation. The power and diversity of the Armed Forces, active Guard and Reserve, the resolve of our fellow citizens, the flexibility in our command to navigate international waters that remain troubled are all essential to our security.

„So if that little thing can do so much, who knows what else we can experience?“

—  Kathy Acker American novelist, playwright, essayist, and poet 1947 - 1997

Kontext: A friend told me that there are these clean and sober dykes that have piercings every couple months just to get high. It's about learning about my body. I didn't know my body could do this. It's not exactly pleasure. It's more like vision. I didn't know the body is such a visionary factory.
Basically we grew up not wanting to know that we had bodies. And it's not as if these piercings are in that deep — it's just on the surface. So if that little thing can do so much, who knows what else we can experience?
