(For example, the human hearing mechanism is one of the most bizarre things in the world, nothing like what a human engineer would come up with.)
Can you come up with a hypothesis for how leaf shapes might be encoded in plant DNA, and then search DNA databases for corroborating evidence?
The third puzzle relates to true negative existential claims, such asthe claim “The golden mountain does not exist.” Here, onceagain, by treating definite descriptions as having a logical formdistinct from that of proper names, Russell is able to give an accountof how a speaker may be committed to the truth of a negativeexistential without also being committed to the belief that thesubject term has reference. That is, the claim that Scott does notexist is false since

However, such an indexed family is often treated as a mere collection of sets. The existence of an indexation is essential in the above formulation, but theusual abuse of notation is to omit the index itself, which is considered . This makes it possible to use simple notations like A+B or AB for the disjoint union of two sets A and B. The squared "U" symbol () is the preferred one (because the is so overloaded). In handwriting and in print, that "squared U" is best drawnas an "inverted pi", to avoid any possible confusion withthe "rounded U" symbol () denoting an union of sets.
Even so, regardless of his many particular contributions, Russell’slasting reputation has also benefited significantly from his constantwillingness to abandon unsupported theories and outdated beliefs. Tohis great credit, when new evidence presented itself, Russell wasalways among the first to take it into account: “Against mywill, in the course of my travels, the belief that everything worthknowing was known at Cambridge gradually wore off. In thisrespect,” says Russell, “my travels were very useful tome” (1967, 133).
In 1954 Russell delivered his famous “Man’s Peril” broadcast onthe BBC, condemning the Bikini H-bomb tests.
