Everything in nature is the result of fixed laws.
Charles DarwinRead
When the sexes differ in beauty, in the power of singing, or in producing what I have called instrumental music, it is almost invariably the male which excels the female.
Interpretation
The quote highlights that in certain traits, such as beauty and musical ability, male members of a species often surpass females.
In this quote, Charles Darwin observes a trend found in various species where males tend to exhibit superior characteristics related to beauty, vocal ability, or instrumental talents compared to females. This phenomenon can be attributed to evolutionary processes, where males may display these traits to attract females or deter rivals, ultimately influencing mating success and species propagation.
In practice
In a lecture on evolutionary biology, this quote could illustrate the concept of sexual dimorphism.
Everything in nature is the result of fixed laws.
The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
I am quite conscious that my speculations run beyond the bounds of true science....It is a mere rag of an hypothesis with as many flaw[s] & holes as sound parts.
We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.
I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
we are always slow in admitting any great change of which we do not see the intermediate steps
A review of seventy-four clinical trials of antidepressants, for example, found that thirty-seven of thirty-eight positive studies [that praised the drugs] were published. But of the thirty-six negative studies, thirty-three were either not published or published in a form that conveyed a positive outcome.
The imposing edifice of science provides a challenging view of what can be achieved by the accumulation of many small efforts in a steady objective and dedicated search for truth.
It is ... a sign of the times-though our brothers of physics and chemistry may smile to hear me say so-that biology is now a science in which theories can be devised: theories which lead to predictions and predictions which sometimes turn out to be correct. These facts confirm me in a belief I hold most passionately-that biology is the heir of all the sciences.
Weve got to go [back to the moon]. But we dont want to stay too long. ... The ultimate goal is Mars.
It is the desire for explanations that are at once systematic and controllable by factual evidence that generates science; and it is the organization and classification of knowledge on the basis of explanatory principles that is the distinctive goal of the sciences.
The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.
