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.
One of the first relational databases for biologists was Biota. Unfortunately, in its early stages of implementation, Biota did not yet have all the elements that my work on taxonomy, systematics, and behavior of katydids required. I decided to develop my own solution, and Mantis was born.
There is a fairly long list of data points, but having a database designed specifically to record them simplifies the record-keeping process tremendously.
Mantis has become an extension of my brain, and extra memory storage space that never forgets anything and thus, I am convinced, is a reason for major memory lapses on my part. Why should I make an effort to remember the author of that paper on the courtship behavior of Cyphoderris when I can quickly look it up?
Of course, I do not carry my laptop with me when out in the first at night, and if anything requires me to make a note I either record it as a voice message on the sound recorder (which I always carry with me), or make a note in a small, waterproof notebook.
Instant availability and portability of data make research in the field infinitely easier for scientists, but what is lost is the feeling of slow accumulation of knowledge and the physical evidence of one’s scientific prestige—the extensive shelves of important-looking volumes and journals.
There is no denying it, the era of paper is fading fast, and I can easily imagine a time when students will be perplexed by the strange, primitive implement known as the pencil. As far as I am concerned, this time cannot come soon enough.
