Balanced sentences (Isocolon)..

Equal sentences give balance.

One sided sentences give imbalance.

Seeing both points of view is right: blindness to the other point of view is dangerous.

If you happen to be a genius, you can string lots of them together:

“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair…” - Dickens loved balanced sentences.

So did Shakespeare:

As Caesar loved me, I weep for him; as he was fortunate, I rejoice at it; as he was valiant, I honour him; but, as he was ambitious, I slew him.

(Brutus in Shakespeare's Julius Caesar.)

Here are some more homely isocolons. 

Climate is what we expect; weather is what we get.

 "It takes a licking, but it keeps on ticking!"(Timex watches.) 

Roses are red, violets are blue...

You can balance the syllables if you like. Read this aloud to see how it works.

Down in a deep, dark hole, sat an old cow munching a beanstalk.
Into her mouth there came yesterday's dinner and tea.

Very soon you get into poetry this way, no doubt as many Rappers have discovered.

Earth hath not anything to show more fair. Dull would he be of soul who could pass by a sight so pleasing in its majesty...

(William Wordsworth: On Westminster Bridge.)

But now we are straying from the subject and we are losing the thread. This is prose: it is not poetry!

Repeating thoughts in a balanced way is impressive: everyone likes a good isocolon.

Cassius Clay/Mohammed Ali, one of the best boxers the world has ever known, said this: 

“Float like a butterfly: sting like a bee.”

Advertisers adore the isocolon. It keeps them in work.

Have a break, have a Kit Kat.
The future's bright. The future's Orange.

Patriots love it: this is the Polish National Anthem:

Poland has not yet succumbed. As long as we remain,
What the foe by force has seized, Sword in hand we'll gain.

The Ghanayan National Anthem:

God bless our homeland Ghana 

And make our nation great and strong,

The simple little isocolon works every time. It is so easy to use.
