The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy’s cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.
The McNamara fallacy, named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.
The fallacy refers to McNamara's belief as to what led the United States to defeat in the Vietnam War—specifically, his quantification of success in the war (e.g., in terms of enemy body count), ignoring other variables.
They mourn, but smile at length; and, smiling, mourn:
The tree will wither long before it fall:
The hull drives on, though mast and sail be torn;
The roof-tree sinks, but moulders on the hall
In massy hoariness; the ruined wall
Stands when its wind-worn battlements are gone;
The bars survive the captive they enthral;
The day drags through though storms keep out the sun;
And thus the heart will break, yet brokenly live on.
I have not loved the world, nor the world me;
I have not flattered its rank breath, nor bowed
To its idolatries a patient knee,—
Nor coined my cheek to smiles, nor cried aloud
In worship of an echo; in the crowd
They could not deem me one of such; I stood
Among them, but not of them; in a shroud
Of thoughts which were not their thoughts, and still could,
Had I not filed my mind, which thus itself subdued.
I have not loved the world, nor the world me,—
But let us part fair foes; I do believe,
Though I have found them not, that there may be
Words which are things,—hopes which will not deceive,
And virtues which are merciful, nor weave
Snares for the falling: I would also deem
O'er others' griefs that some sincerely grieve;
That two, or one, are almost what they seem,—
That goodness is no name, and happiness no dream.
There is a pleasure in the pathless woods,
There is a rapture on the lonely shore,
There is society where none intrudes,
By the deep Sea, and music in its roar:
I love not Man the less, but Nature more.
