Hypotheses are what we lack the least.
Sentiment: NEGATIVE
Hypotheses should be subservient only in explaining the properties of things but not assumed in determining them, unless so far as they may furnish experiments.
To rewrite history on the bases of hypotheses which have not materialized is not only a fruitless task, but, in my eyes, meaningless.
You can't prove any hypothesis, you can only improve or disprove it.
There is little evidence that our individual intelligence has improved through recorded history.
In science, each new result, sometimes quite surprising, heralds a step forward and allows one to discard some hypotheses, even though one or two of these might have been highly favored.
Nothing is so firmly believed as what we least know.
Good tests kill flawed theories; we remain alive to guess again.
A few observation and much reasoning lead to error; many observations and a little reasoning to truth.
In order to shake a hypothesis, it is sometimes not necessary to do anything more than push it as far as it will go.
The plain fact is that there are no conclusions.
