Simplicity

Simplicity is the property, condition, or quality of being simple or un-combined. It often denotes beauty, purity, or clarity. Simple things are usually easier to explain and understand than complicated ones. It is also a term used to denote candor, guilelessness, innocence, straightforwardness, and freedom from duplicity.

Plurality ought never be posited without necessity. ~ William of Occam

Simplicity is the most deceitful mistress that ever betrayed man.
- Henry Adams, The Education of Henry Adams (1907).

Simplicity is very complicated.
- Armen Agop, quoted by Eltorie, Aida, (2009) Undercurrent, Contemporary Egyptian Art. Art Sawa. Dubai. pg. 32

Do nothing but what is necessary. ... By this rule a man has the double pleasure of making his actions good and few into the bargain. For the greater part of what we say and do, being unnecessary, if this were but taken away, we should have both more leisure and less disturbance. And therefore before a man sets forward, he should ask himself this question, "Am I not upon the verge of something unnecessary?"
- Marcus Aurelius Antonius, Meditations, Book 4 (c. AD 121–180)

Clancy got a very simple view of the world. Good versus evil. Evil seems to get the upper hand. Good triumphs with vastly superior automatic weapons!

Simplicity — the art of maximizing the amount of work not done — is essential.

'Tis the gift to be simple, 'tis the gift to be free.

My views are near to those of Spinoza: admiration for the beauty of and belief in the logical simplicity of the order and harmony which we can grasp humbly and only imperfectly. I believe that we have to content ourselves with our imperfect knowledge and understanding and treat values and moral obligations as a purely human problem — the most important of all human problems.
- Albert Einstein, in a letter to Murray W. Gross (26 April 1947), quoted in Einstein and Religion (1999).

What I'm really interested in is whether God could have made the world in a different way; that is, whether the necessity of logical simplicity leaves any freedom at all.
- Albert Einstein, as quoted by Erner Gabor Strauss, his assistant from 1944 - 1948, as translated in The Scientific Imagination: Case Studies (1978) by Gerald Holton, p. xii.
- Variant translation: What I am really interested in is knowing whether God could have created the world in a different way; in other words, whether the requirement of logical simplicity admits a margin of freedom.

- William Gaddis, The Recognitions (1955) p. 457; "Simplicity is the ultimate sophistication" was also used as an early slogan at Apple Computer in 1977 (introduction of the Apple II personal computer), and has also been attributed to Leonardo Da Vinci, but no published occurrence of such an attribution has yet been located prior to one in Wisdom Through the Ages : Book Two (2003) by Helen Granat, p. 225.

In a country as hot as India, a person really requires very few essentials in order to live: one vegetarian meal a day, bread rice, vegetables and lentils, two pieces of clothing to wear, a mat, a blanket, a lota, a water container - just enough to fulfill our bodily requirements. In fact, we don't have a bathroom, shower or toilet here but have to go down to the river to wash, and for everything else we squat among the stones. Cooking takes place outside on an open fire and we sleep on the floor, tucked up on a mat in any place we can find. There is no need for shoes, for it is better to walk barefoot, nor a suitcase because it is sufficient to wrap one's clothes up in a bundle. Mother India is a great teacher of simplicity.
- Gaura Devi (2001). Fire of Transformation. My life with Babaji. P. 74

To me more dear, congenial to my heart,
One native charm, than all the gloss of art.

Science can be very complicated, but there is nothing in its definition that implies it must be, or requires descriptions of science to be written in any sort of special language that only scientists understand. ... The detail and implications of Einstein's theory of relativity may be beyond the understanding of many of us, but it can be described in simple language, which is what Einstein himself used in his own writing.

Christianity does not proceed from the simple in order then to become interesting, witty, profound, a poet, a philosopher, etc. No it is just the opposite: here one begins and then becomes more and more simple, arrives at the simple.

If we study the history of science we see happen two inverse phenomena, so to speak. Sometimes simplicity hides under complex appearances; sometimes it is the simplicity which is apparent, and which disguises extremely complicated realities.
...What is more complicated than the confused movements of the planets? What simpler than Newton's law?
...In the kinetic theory of gases, one deals with molecules moving with great velocities, whose paths, altered by incessant collisions, have the most capricious forms... The observable result is Mariotte's simple law. ...The law of great numbers has reestablished simplicity in the average.
...No doubt, if our means of investigation should become more and more penetrating, we should discover the simple under the complex, then the complex under the simple, then again the simple under the complex, and so on, without our being able to foresee what will be the last term. We must stop somewhere, and that science may be possible, we must stop when we have found simplicity. This is the only ground on which we can rear the edifice of our generalizations.

Quotes reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895).

If our love were but more simple,
We should take Him at His word;
And our lives would be all sunshine
In the sweetness of the Lord.
- Frederick William Faber, p. 545.

"Blessed are the poor in spirit." Blessed are they who are stripped of every thing, even of their own wills, that they may no longer belong to themselves.
- François Fénelon, p. 544.

God would behold in you a simplicity which will contain so much the more of His wisdom as it contains less of your own.
- François Fénelon, p. 544.

As to our friend, I pray God to bestow upon him a simplicity that shall give him peace. Happy are they indeed who can bear their sufferings in the enjoyment of this simple peace and perfect acquiesence in the will of God.
- François Fénelon, p. 545.

True simplicity regards God alone; it has its eye fixed upon Him, and is not drawn toward self; and it is as pleased to say humble as great things. All our uneasy feelings and reflections arise from self-love, whatever appearance of piety they may assume. The lack of simplicity inflicts many wounds. Go where we will, if we remain in ourselves, we shall carry everywhere our sins and our distresses. If we would live in peace, we must lose sight of self, and rest in the infinite and unchangeable God.
- Madame Guyon, p. 544.

Simplicity and purity are the two wings by which a man is lifted above all earthly things. Simplicity is in the intention — purity in the affection. Simplicity tends to God,— purity apprehends and tastes Him.
- Thomas à Kempis, p. 545.

He sows June fields with clover, and the world
Broadcasts with little common kindnesses.
The plain good souls He sends us, who fulfill
Life's homely duties in the daily path
With cheerful heart, ambitious of no more
Than to supply the wants of friend and kin,
Yet serve God's higher love to human hearts;
Giving a secret sweetness to the home,
The hidden fragrance of a kindly heart,
The simple beauty of a useful life,
That never dazzles, and that never tires.
- Samuel Longfellow, p. 544.

Simpler manners, purer lives; more self-denial; more earnest sympathy with the classes that lie below us, nothing short of that can lay the foundations of the Christianity which is to be hereafter, deep and broad.
- Frederick William Robertson, p. 545.
