“How paramount the future is to the present when one is surrounded by children.”

Great is the power of steady misrepresentation.

There is no fundamental difference between man and animals in their ability to feel pleasure and pain, happiness, and misery.

Man is descended from a hairy, tailed quadruped, probably arboreal in its habits.

I would give absolutely nothing for the theory of Natural Selection, if it requires miraculous additions at any one stage of descent.

In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment.

I am not apt to follow blindly the lead of other men.

Everything in nature is the result of fixed laws.

I am not the least afraid to die.

From my early youth I have had the strongest desire to understand or explain whatever I observed. To group all facts under some general laws.

Only the fittest will survive.

The loss of tastes for poetry and music is a loss of happiness.

To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact.

I have tried lately to read Shakespeare, and found it so intolerably dull that it nauseated me.

What a book a devil’s chaplain might write on the clumsy, wasteful, blundering, low, and horribly cruel work of nature!

It is impossible to concieve of this immense and wonderful universe as the result of blind chance or necessity.

Perfection is terrible, it cannot have children.

There’s nothing more satisfying than seeing a happy and smiling child.

Some children are spoiled and it is not their fault, it is their parents.

It is a poverty to decide that a child must die so that you may live as you wish.

The more risks you allow your children to make, the better they learn to look after themselves.

The most interesting information come from children, for they tell all they know and then stop.

One of the greatest gifts adults can give – to their offspring and to their society – is to read to children.
