Aristotle Categorized Species as Immutable, the Theory of...

Aristotle noted three characteristics of his concept of species. First, each species is a whole. It is comprehensive, representative of all the objects embraced within it, and any one of these objects may be used as an example of all others. The species tree, for example, embraces all trees whether they are used for timber or for firewood; and any given tree may exemplify the species which includes all trees. Second, any one species comprises objects which have common or identical elements o...

 How to Not Fear Death

Some old people are oppressed by the fear of death. In the young there there is a justification for this feeling. Young men who have reason to fear that they will be killed in battle may justifiably feel bitter in the thought that they have been cheated of the best things that life has to offer. But in an old man who has known human joys and sorrows, and has achieved whatever work it was in him to do, the fear of death is somewhat abject and ignoble. The best way to overcome it—so at least ...

 How Media-Metaphors Change Thought

But our media-metaphors are not so explicit or so vivid as these, and they are far more complex. In understanding their metaphorical function, we must take into account the symbolic forms of their information, the source of their information, the quantity and speed of their information; the context in which their information is experienced. Thus, it takes some digging to get at them, to grasp, for example, that a clock recreates time as an independent, mathematically precise sequence; that wr...

 Online Comment Culture

Being an active commenter felt like being an internet socialite, part of an elite society of people who put their voice out there instead of lurked. And my fellow internet socialites responded in turn. Some upvoted, responded, debated. Some liked what I said, some hated it. A few of my comments made it to the top and became a fountain of dopamine. A few comments made it to the very bottom too. That can happen with 16 years of commenting history. [...] Various estimates of lifetime human ac...

 Where One Puts the Mind

We say that: If one puts his mind in the action of his opponent's body, his mind will be taken by the action of his opponent's body. If he puts his mind in his opponent's sword, his mind will be taken by that sword. If he puts his mind in thoughts of his opponent's intention to strike him, his mind will be taken by thoughts of his opponent's intention to strike him. If he puts his mind in his own sword, his mind will be taken by his own sword. If he puts his mind in his own intention of ...

 Someone Will be Happy You are Dead

There is no man so fortunate that there shall not be by him when he is dying some who are pleased with what is going to happen. Suppose that he was a good and wise man, will there not be at last some one to say to himself, Let us at last breathe freely being relieved from this schoolmaster? It is true that he was harsh to none of us, but I perceived that he tacitly condemns us.- This is what is said of a good man. But in our own case how many other things are there for which there are many wh...

 On Balancing Work and Rest

In he morning when thou risest unwillingly, let this thought be present- I am rising to the work of a human being. Why then am I dissatisfied if I am going to do the things for which I exist and for which I was brought into the world? Or have I been made for this, to lie in the bed-clothes and keep myself warm?- But this is more pleasant.- Dost thou exist then to take thy pleasure, and not at all for action or exertion? Dost thou not see the little plants, the little birds, the ants, the spid...

 Aurelius Quotes on Mindfulness

2.8 Rarely is a person seen to be in a bad way because he has failed to attend to what is happening in someone else’s soul, but those who fail to pay careful attention to the motions of their own souls are bound to be in a wretched state. 2.11 Let your every action, word, and thought be those of one who could depart from life at any moment. 3.4 Do not waste what remains of your life in forming impressions about others, unless you are doing so with reference to the common good. For you are...

 Why Humans Evolved to be Active

Humans of all to be much more physically active than our ape ancestors. Typical chimpanzee walks maybe two to three kilometers a day, and they take maybe what, three, 4,000 steps a day. A typical hunter-gatherer takes about 15 to 20,000 steps a day. Per kilo hunter-gatherers spend about twice as much energy per kilo on being physically active per day than our ape cousins. And importantly, that physical activity occurs as we age, right? So Americans are pretty inactive, as we all know. A typ...

 "Race" in D&D

As a social scientist who studies male-dominated subcultures, I have done research that put me in spaces where I delved into reactions to issues of race in gaming. A key question is this: Given how charged the term race has been, why would games use it to discuss differences that have nothing to do with the way we traditionally use the word? Dungeons & Dragons is not the only game to use the term in this way; so have many other digital and analog fantasy offerings. But the celebrated game...
