Everything in nature is the result of fixed laws.
Charles DarwinRead
...I have always maintained that, excepting fools, men did not differ much in intellect, only in zeal and hard work; and I still think there is an eminently important difference.
Interpretation
Intellect varies little among men; the key distinctions lie in their passion and effort.
In this quote, Charles Darwin suggests that the differences in intelligence among individuals are minimal. Instead, what truly sets people apart is their level of enthusiasm and dedication to their pursuits, implying that hard work and passion are significant determinants of success and achievement.

The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.

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
These heavy troubles are heralds of weighty mercies.
You always want to quit while you are ahead. You don't want to be like a fighter who stays too long in the ring until you're not performing at your best.
There's no shortage of remarkable ideas, what's missing is the will to execute them.
They think that intelligence is about noticing things are relevant (detecting patterns); in a complex world, intelligence consists in ignoring things that are irrelevant (avoiding false patterns)
Don't, Sir, accustom yourself to use big words for little matters.
If you knew who walked beside you at all times, on the path that you have chosen, you could never experience fear or doubt again.
