# Pretty quotes

As you could perhaps guess from the epigraph on my homepage, I like quotes. Here's a small collection I've built up so far (Excluding some of the more well-known ones, like the Darwin quote that everyone likes). Of course, just because I've included a quote doesn't mean I completely agree with everything it says or implies, it just means I liked the quote. You can also find a list of quotes on Allison Shaw's website.

## On Modelling

- Two cliché quotes in one :)

“Our future advances will not be concerned with universal laws, but instead with universal approaches to tackling particular problems.”

“The epistemic aim of science is not truth, but understanding”

“The simplicity and straightforwardness of a pattern at once increase its usefulness for limited humans and decrease its universality in a world that is neither simple nor straightforward”

“We only need models because our brains suffer from too many limitations and are not able to consider all sides of a complicated argument in a balanced way”

“we attempt to treat the same problem with several alternative models each with different simplifications but with a common biological assumption. [...] Hence our truth is the intersection of independent lies.”

“A good theoretical model of a complex system should be like a good caricature: it should emphasize those features which are most important and should downplay the inessential details. Now the only snag with this advice is that one does not really know which are the inessential details until one has understood the phenomena under study. Consequently, one should investigate a wide range of models and not stake one’s life (or one’s theoretical insight) on one particular model only”

“There are worse sins for a scientist than to be wrong. One is to be trivial”

“The result has been forty years of bewilderment about what he meant, whereas if he had been willing to make a slight sacrifice of strict mathematical propriety (as I have done) he could have expressed himself in a way that everyone would have understood”

- George Price (speaking about Fisher)

“Like most mathematicians, he takes the hopeful biologist to the edge of a pond, points out that a good swim will help his work, and then pushes him in and leaves him to drown.”

- Charles Elton (speaking about Lotka)

“The economic world is a misty region. The first explorers used unaided vision. Mathematics is the lantern by which what before was dimly visible now looms up in firm, bold outlines. The old phantasmagoria disappear. We see better. We also see further.”

“At any time, there is only a thin layer separating what is trivial from what is impossibly difficult. It is in that layer that discoveries are made”

- Andrei Kolmogorov

“An orgy of regression failed-

so algebra I then assailed,

with all the fun that this entailed

I modelled….and results prevailed

My future now was quite secure,

And to the field I go no more,

Papers, papers by the score

Full of sums and such a bore”

“we should be careful not to be distracted by the biological equivalents of friction, if we are interested in discovering the biological equivalents of inertia.”

“There is only one thing which is more unreasonable than the unreasonable effectiveness of mathematics in physics, and this is the unreasonable ineffectiveness of mathematics in biology”

“Well, the stripes are easy but what about the horse part?”

- Alan Turing (According to Francis Crick), speaking about Turing Patterns

“The heart and soul of much mathematics consists of the fact that the ‘same’ object can be presented to us in different ways. [...] This issue has been with us, of course, forever: the general question of

*abstraction*, as separating what we want from what we are presented with.[...] if it is*whiteness*we want to think about, we must somehow separate it from*white horse, white house, white hose*and all the other white things that it invariably*must*come along with, in order for us to experience it at all”

## On Generality and Knowledge

“Somewhere [ ... ] between the specific that has no meaning and the general that has no content there must be, for each purpose and at each level of abstraction, an optimum degree of generality”

“I believe there can be great benefit to shifting the emphasis away from an organizational structure based on the useful lines of inquiry carved out by researchers, to one based on the fundamental processes that underlie community dynamics and patterns.”

“General events are only seen by ecologists with rather blurred vision. The very sharp-sighted always find discrepancies and are able to see that there is no generality, only a spectrum of special cases”

“To do science is to search for repeated patterns, not simply to accumulate facts”

“The grand aim of all science [is] to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.”

- Albert Einstein (according to Lincoln Barnett)

“Wir müssen wissen – wir werden wissen” ("We must know – we will know")

- David Hilbert, Mathematician

“ignoramus et ignorabimus” ("we do not know and will not know”)

- Emil du Bois-Reymond, Biologist

## On Ecology and evolution

“In nature, nothing exists alone.”

“There are two ways to be a student of nature. You can collect, preserve, dissect and describe it, accurate in every sinew and cell. Or you can breathe along with it, engage with its messiness and feel what it feels to be a thing in the world.”

“The dry-balls cannot possibly learn a thing every starfish knows in the core of his soul and in the vesicle between his rays. He must, so know the starfish and the student biologist who sits at the feet of living things, proliferate in all directions.”

“The theory of evolution by natural selection is an ecological theory—founded on ecological observation by perhaps the greatest of all ecologists. It has been adopted by and brought up by the science of genetics, and ecologists, being modest people, are apt to forget their distinguished parenthood.”

“The mathematical theory of evolution is in a somewhat unfortunate position, too mathematical to interest most biologists and not sufficiently mathematical to interest most mathematicians”

“As good evolutionary biologists we should go once a year to the zoo and visit the elephant. We should greet it and say ‘Elephant, I believe you got about by random mutation’”

- John Maynard Smith, on evolutionary biology's attempts at explaining the complexity of life

“It is an occupational risk of biologists to claim, towards the end of their careers, that the problems which they have not solved are insoluble.”

“For a biologist, the alternative to thinking in evolutionary terms is not to think at all”

“The development of a definite biological system is conditioned not only on its state at a given moment [...] the past history of the system exerts a powerful influence together with its present state”

“Evolution is cleverer than you are”

“What we want to know is how the biological forces of natality and mortality are so integrated and correlated in their action as to lead to a final result in size of population which follows this particular curve rather than some other one”

“Unlike population genetics, ecology has no known underlying regularities in its basic processes”

“Community ecology is often perceived as a mess, given the seemingly vast number of processes that can underlie the many patterns of interest, and the apparent uniqueness of each study system. However, at the most general level, patterns in the composition and diversity of species–the subject matter of community ecology–are influenced by only four classes of process: selection, drift, speciation, and dispersal.”

“Very few high-level features of the world have necessary and sufficient properties. In everyday life and in ecology, concepts are fuzzy, being held together by an open-ended set of correlated properties”

– Evan C. Johnson, Oscar Godoy, and Alan Hastings (Appendix B.4)

## Miscellaneous

“The ideal scientist thinks like a poet and works like a bookkeeper, and I suppose that if gifted with a full quiver, he also writes like a journalist.”
