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.
When the scientific method came into being, it gave us a new window on the truth; namely, a method by laboratory-controlled experiments to winnow true hypotheses from false ones.
True science is never speculative; it employs hypotheses as suggesting points for inquiry, but it never adopts the hypotheses as though they were demonstrated propositions.
I think philosophers can do things akin to theoretical scientists, in that, having read about empirical data, they too can think of what hypotheses and theories might account for that data. So there's a continuity between philosophy and science in that way.
All science is based on models, and every scientific model comprises three distinct stages: statement of well-defined hypotheses; deduction of all the consequences of these hypotheses, and nothing but these consequences; confrontation of these consequences with observed data.
When I was a teenager, science meshed with my developing ideals - such as the challenge to authority that was central to punk rock. In science, anyone from any walk of life could make a discovery that would overturn prevailing hypotheses. And that was a cause for celebration among scientists.
Research is so unpredictable. There are periods when nothing works and all your experiments are a disaster and all your hypotheses are wrong.
So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.
To rewrite history on the bases of hypotheses which have not materialized is not only a fruitless task, but, in my eyes, meaningless.
Hypotheses are what we lack the least.
