论贵粟疏 晁 错 圣王在上而民不冻饥者，非能耕而食之，织而衣之也，为开其资财之道也。故尧、禹有九年之水，汤有七年之旱，而国亡捐瘠者，以畜积多而备先具也。今海内为一，土地人民之众不避汤、禹，加以亡天灾数年之水旱，而畜积未及者，何也?地有遗利，民有余力，生谷之土未尽垦，山泽之利未尽出也，游食之民未尽归农也。 民贫，则奸邪生。贫生于不足，不足生于不农，不农则不地著，不地著则离乡轻家，民如鸟兽，虽有高城深池，严法重刑，犹不能禁也。夫寒之于衣，不待轻暖；饥之于食，不待甘旨；饥寒至身，不顾廉耻。人情一日不再食则饥，终岁不制衣则寒。夫腹饥不得食，肤寒不得衣，虽慈母不能保其子，君安能以有其民哉?明主知其然也，故务民于农桑，薄赋敛，广畜积，以实仓廪，备水旱，故民可得而有也。 民者，在上所以牧之，趋利如水走下，四方亡择也。夫珠玉金银，饥不可食，寒不可衣，然而众贵之者，以上用之故也。其为物轻微易藏，在于把握，可以周海内而亡饥寒之患。此令臣轻背其主，而民易去其乡，盗贼有所劝，亡逃者得轻资也。粟米布帛生于地，长于时，聚于力，非可一日成也；数石之重，中人弗胜，不为奸邪所利，一日弗得而饥寒至。是故明君贵五谷而贱金玉。 今农夫五口之家，其服役者不下二人，其能耕者不过百亩，百亩之收不过百石。春耕，夏耘，秋获，冬藏。伐薪樵，治官府，给徭役；春不得避风尘，夏不得避暑热，秋不得避阴雨，冬不得避寒冻，四时之间亡日休息；又私自送往迎来，吊死问疾，养孤长幼在其中。勤苦如此，尚复被水旱之灾。急政暴虐，赋敛不时，朝令而暮改。当具有者半贾而卖，亡者取倍称之息。于是有卖田宅、鬻子孙以偿责者矣。而商贾大者积贮倍息，小者坐列贩卖，操其奇赢，日游都市，乘上之急，所卖必倍。故其男不耕耘，女不蚕织，衣必文采，食必粱肉。亡农夫之苦，有阡陌之得。因其富厚，交通王侯，力过吏势，以利相倾。千里游遨，冠盖相望，乘坚策肥，履丝曳缟。此商人所以兼并农人，农人所以流亡者也。今法律贱商人，商人已富贵矣；尊农夫，农夫已贫贱矣。故俗之所贵，主之所贱也；吏之所卑，法之所尊也。上下相反，好恶乖迕，而欲国富法立，不可得也。 方今之务，莫若使民务农而已矣。欲民务农，在于贵粟；贵粟之道，在于使民以粟为赏罚。今募天下入粟县官，得以拜爵，得以除罪。如此，富人有爵，农民有钱，粟有所渫。夫能入粟以受爵，皆有余者也；取于有余，以供上用，则贫民之赋可损，所谓损有余，补不足，令出而民利者也。顺于民心，所补者三：一日主用足，二曰民赋少，三日劝农功。今令：“民有车骑马一匹者，复卒三人。”车骑者，天下武备也，故为复卒。神农之教曰：“有石城十仞，汤池百步，带甲百万，而亡粟，弗能守也。”以是观之，粟者，王者大用，政之本务。令民入粟受爵至五大夫以上，乃复一人耳。此其与骑马之功相去远矣。爵者，上之所擅，出于口而亡穷；粟者，民之所种，生于地而不乏。夫得高爵与免罪，人之所甚欲也。使天下人入粟于边，以受爵免罪，不过三岁，塞下之粟必多矣。

There are many differences in the ways women and men deal with stress. There are a number of factors that play into this. Traditionally, women, more than men, take on the role of primary family caregivers. This means that all of a family's health concerns fall on the shoulders of the women, along with the stress that brings. A woman will tend to put everyone at ease before herself and eventually sacrifice her own health and well-being. She doesn't care if she is suffering from a cold at work. Once her child is sick, she will drop everything else to take care of him. If you ask men and women to describe their reactions to stress, their answers will be completely different. Men usually characterize their stress reactions as feelings of rage or sleeplessness. Women usually say that their reaction to stress is wanting to cry. A majority of women also say that they are prone(易于发生的)to overeating when under stress. Most studies on stress have only been on men and how men respond. These studies are where we get the familiar "fight or flight" notions(观念). For decades this was how scientists assumed all humans behaved. Only recently have scientists begun performing stress tests on groups of women and the results are not at all what our male counterparts would have indicated. In most cases, women did not react to stress by wanting to "fight or flight". Instead, their instincts(直觉)were to nurture. This new model for how females deal with stress has been described as the "tend and befriend" paradigm by its discoverer, Dr. Shelley Taylor. A woman's instincts are naturally to Drotect or tend to their children and themselves. Then women seek out other women that could help them through. Pursuing comfort through a connection is the befriend aspect. Women are thought to have the same rush of hormones(荷尔蒙)as men when under stress, but the types of hormones differ.
