The Nominal Fallacy
The nominal fallacy is the error of believing that the label carries explanatory information. An instance of the nominal fallacy is most easily seen when the meaning or importance of a term or concept shrinks with knowledge. One example of this would be the word “instinct.” “Instinct” refers to a set of behaviors whose actual cause we don’t know, or simply don’t understand or have access to, and therefore we call them instinctual, inborn, innate. Often this is the end of the expl...Stuart Firestein explains why naming is not explaining.

Humanity has Reached the Hatching Point
To begin our position-fixing aboard our Spaceship Earth we must first acknowledge that the abundance of immediately consumable, obviously desirable or utterly essential resources have been sufficient until now to allow us to carry on despite our ignorance. Being eventually exhaustible and spoilable, they have been adequate only up to this critical moment. This cushion-for-error of humanity's survival and growth up to now was apparently provided just as a bird inside of the egg is provided wi...Thinking of our Earth as an egg, we have been living on the yolk so far. We are reaching the point, by burning our fossile fuels off and exceeding the production capacity of our agriculture, where our intellect must launch us into the stars.

An Egg is a Chemical Process
An egg is a chemical process, but it is not a mere chemical process. It is one that is going places—even when, in our world of chance and contingency, it ends up in an omelet and not in a chicken. Though it surely be a chemical process, we cannot understand it adequately without knowing the kind of chicken it has the power to become.But one with a long, complex history ahead of it.

Metaphor for the Spread of Disease
To choose a rough example, think of a thorn which has stuck in a finger and produces an inflammation and suppuration. Should the thorn be discharged with the pus, then the finger of another individual may be pricked with it, and the disease may be produced a second time. In this case it would not be the disease, not even its product, that would be transmitted by the thorn, but rather the stimulus which engendered it. Now supposing that the thorn is capable of multiplying in the sick body, or ...Folksonomies: metaphor

Mammals Produce Useless Yolks
Vestigial genes can go hand in hand with vestigial structures. We mammals evolved from reptilian ancestors that laid eggs. With the exceptions of the “monotremes” (the order of mammals that includes the Australian spiny anteater and duck-billed platypus), mammals have dispensed with egg-laying, and mothers nourish their young directly through the placenta instead of by providing a storehouse of yolk. And mammals carry three genes that, in reptiles and birds, produce the nutritious protein...Because they evolve from egg-laying reptiles, they have dead genes for producing yolks and even produce yolks in the placenta.
