In Physics, he asked by way of example why front teeth regularly grow sharp, and back teeth broad, in a fashion that is good for an animal. He claimed that we must go beyond just the interaction of particles, because it cannot simply be coincidence

Bacon’s central argument was not exactly that this was wrong, but rather that it was impractical.

The second element of his theory was his belief that humans tend to overinterpret data into unreliable patterns and therefore leap to faulty conclusions,

The result was a closed intellectual system whose adherents spent their energies in ceaseless argumentation based on false premises, rather than seeking new information.

Bacon proposed a new method (novum organum) that would start with the meticulous construction of factual knowledge as a foundation for belief

The ultimate goal of Baconian science is not philosophical truth; it is improved engineering.

Bacon had a clear understanding of the roles of what today we call basic and applied research. Although he saw the ultimate goal of science as material benefit, he believed that, paradoxically, focusing on slowly building sufficient experimental knowledge to develop general physical laws (“experiments of Light”), rather than trying to immediately solve specific practical problems (“experiments of Fruit”),
Note:SCIENZA DI BASE

Yellow highlight | Page: 9

he asserted the primacy of careful experiments as the initial building blocks of scientific knowledge.
Note:L ESPERIMENTO MATERIALE

Yellow highlight | Page: 9

Bacon’s degree of focus on experimentation at the expense of theorizing can be caricatured.
Note:RESTA PICO DI BACONE.....MA NN MINIMIZZIAMO

Yellow highlight | Page: 9

It was not until many years later that the concept of the controlled experiment (carefully changing only one potential causal factor and observing the result) was more rigorously distinguished from nonexperimental observation than in Bacon’s somewhat impressionistic “verified, weighed, and counted” description.
Note:ESPERIMENTO E OSSERVAZIONE

Yellow highlight | Page: 10

Bacon attempted to define a process of scientific experimentation and inference, but in this he failed; the detailed method he proposed has not been used by scientists in practice. He was never able to explain exactly how the induction of general physical laws from individual observations should work at an algorithmic or logical level.

“simple enumeration” is not what we’re after, that the development of cause-and-effect rules is central to practical knowledge:

we can never be sure of a cause-and-effect rule developed through induction.

to the extent that my belief in a particular cause-and-effect relationship relies on induction, this belief must always remain provisional.

This might seem like the kind of thing that only a philosopher with too much time on his hands could care about, and in fact, Hume was careful to ridicule the seemingly airy-fairy nature of his concern before his readers could do it for him.

The Problem of Induction becomes a practical problem when we begin to depart from the arena in which common sense works.
Note:IL SENSO COMUNE

Yellow highlight | Page: 14

The Problem of Induction can be restated usefully as the observation that there may always be hidden conditionals to any causal rule that is currently believed to be valid.
