Laugh as much as you choose, but you will not laugh me out of my opinion.

My pain may be the reason for somebody's laugh.
But my laugh must never be the reason for somebody's pain.

I have cried even when the laugh did choke me. But no more think that I am all sorry when I cry, for the laugh he come just the same. Keep it always with you that laughter who knock at your door and say, ‘May I come in?’ is not true laughter. No! He is a king, and he come when and how he like. He ask no person, he choose no time of suitability. He say, ‘I am here.

"Laughter, on the other hand, " Petrarch went on, "is an explosion that tears us away from the world and throws us back into our own cold solitude. Joking is a barrier between man and the world. Joking is the enemy of love and poetry. That's why I tell you yet again, and you want to keep in mind: Boccaccio doesn't understand love. Love can never be laughable. Love has nothing in common with laughter."

While the laughter of joy is in full harmony with our deeper life, the laughter of amusement should be kept apart from it. The danger is too great of thus learning to look at solemn things in a spirit of mockery, and to seek in them opportunities for exercising wit.

Laughter is a protest scream against death, against the long goodbye. It’s a defense against unhappiness and depression.

Without love and laughter there is no joy; live amid love and laughter.

If there is no laughter, the soul dies. (p186)

Gentlemen, why do you not laugh? With the fearful strain that is upon me day and night, if I did not laugh, I should die.

Laughter is wine for the soul — laughter soft, or loud and deep, tinged through with seriousness. Comedy and tragedy step through life together, arm in arm, all along, out along, down along lea. A laugh is a great natural stimulator, a pushful entry into life; and once we can laugh, we can live. It is the hilarious declaration made by man that life is worth living.

[I]t would be a pity if laughter should ever become, like rhetoric and the arts, a habit.

I dearly love a laugh... I hope I never ridicule what is wise or good. Follies and nonsense, whims and inconsistencies do divert me, I own, and I laugh at them whenever I can.

Your Pain May Give
Laugh To Somebody
But
Your Laugh Shouldn't
Give Pain To Anybody

Isn't it only through laughter that we become one with the gods and thus can endure life and can overcome all the horror and waste and suffering here on earth? Like tonight, watching all those brave men meet their fate here, on this shore, on this gentle night, through a karma ordained a thousand lifetimes ago, or perhaps even one.

Isn’t it only through laughter we can stay human?
