Do we generally use reason or emotion (or other wok) to make ethical decisions? Which one should we use?

I'm not good with choosing sides. Do we base our decisions off of our emotions or reasoning? Ethics may seem emotionally motivated, I mean, why would we make an entire system based on feelings of sentimental values otherwise? However, there are fringes of logic in every socially acceptable moral value. If we were to see every issue through an emotionally-motivated lens, it would be difficult (and at times, impossible) to comprehend why there are multiple views regarding a single issue; however, with logic, we are able to reach compromise, (hopefully) understand why someone may think a certain way, and even change our opinions. Without logic, we wouldn't see progression in society, as all our emotionally-driven decisions would remain static. However, it's easier to appeal to someone from an emotional standpoint than a logical one. Our reasoning is individualized but emotion is a common ground we all share, and through this, we are able to exploit it to ignite change. 

This isn't to say that there aren't certain cases where a person makes an ethical decision (ethical in this situation meaning that it doesn't hurt any living creature or break any laws) using only logic or only reason. For example, if I decide to marry an ugly old rich man with a horrible personality, that decision is logical because I want to be financially secure while engaging in as little work as possible. I clearly didn't choose to marry him because I feel any emotional attachment to him. However, if I decide that a movie is sad, there isn't any reasoning behind that, it's simply the way I feel. But more often than not, more complex ethical decisions use a mix of logic and emotion. 

So, is there a correct way to make decisions? Again, I'm not good with choosing sides. Whether to be ruled by logic or emotion is determined on a case-by-case basis. Sometimes it's both, sometimes it's neither. There's no true way to determine how someone can make decisions because we're not that person. There's no way to calculate every single consequence stemming from a single decision. Just go with the flow, man.

What are the three biggest problems facing universities today? What problems of knowledge do these represent?

These issues faced by universities are in no particular order.

Prestige: Rankings have become the be-all, end-all for a majority of universities in the U.S. The top 50 schools in the U.S. are constantly switching spots, as their rankings vary from year to year. These universities find small ways to influence their rankings, such as attracting more applications to the school (this is a factor that influences rankings, and is often why you see emails from colleges asking you to apply) while accepting the same number of students, in order to climb up the ladder and convince teens to invest their time and money in the college. Schools that stay in the lower ranks invest in more superficial things, such as recreation complexes, food, or sports teams, in order to attract potential students for reasons other than academics. Community colleges, which often provide affordable and valuable programs, are shunned in general society, placing a price on knowledge.
Problems of Knowledge:
Emotion - The construction of  these extravagant facilities is to ensure the well-being and enjoyment of the "college experience" by the students. However, does this help or hinder a student's ability to learn? Do all the distractions on campus detract from the reason why people study there (this applies especially to "party schools")? In addition, many people become the value of their school, if a smart person with a good work ethic goes to a community college for any number of reasons, does this take away from their good characteristics as a whole?

Cost: The increasing cost of college has put a burden on both students and parents. Students in the U.S. are paying more than any other generation has had to do so in the past. As people in student debt begin to default on their loans and a market bubble forms around universities, it becomes more and more obvious that this is not a sustainable system.
Problems of Knowledge:
Ethics - The price tag on tuition creates a divide between the value of knowledge and the costs associated with living on a college campus. Is it  right to put a price on knowledge? Is knowledge quantifiable? If so, is the cost of going to university a good measurement?

Value: With growing concern over the cost of college and a university's resources, the question of whether or not a college education is useful begins to appear more and more. If a college is unable to provide sustainable, appropriate employment to its graduates, is it really worth all the money and time? If a student majors in an impracticable discipline, such as philosophy, is it on the university's shoulders to be honest with the student about their choices, or is it solely the student's responsibility to major in something practical, rather than something they are passionate about?
Problems of Knowledge:
Language - Is it time for universities to be honest and tell students that college is not a place to"follow your dreams" if it is not practical? Should colleges be honest about how they can approach job placement in their advertising?
