It's been suggested that without the fear of consequence for one's choices (such as an eternity in Hell) that nothing would matter (people would make choices outside of axiom of moral goodness), which leads me to believe that the moral goodness of many is a result of fear of consequence for their actions.
Is fear the only reason many choose to be good?
Assuming your moral compass points in the direction of benevolence, what specifically keeps you on that path?
I have found that there are inner drives and impulses that my personality has had to deal with and that in dealing with these inner drives and impulses I have become more able to act morally as a result. I think that modern developments and ideas about human psychology have offered new ways to understand how we can manage ourselves and those inner influences which are problematic to our personalities' assumptions.
We can tell what are the rough spots in our personalities when we act selfishly or fearfully or with a great deal of emotion beyond what we later deem was necessary. Something in us is misaligned or under-developed and this leads us into all sorts of morally complicated choices. Understanding one's natural inclinations of personality type, how that triggers your "shadow" and how to manage and nurture your personality by feeding all of its needs in a balanced way. In part this means finding those challenges that allow you to choose some level of control rather than to suffer a loss of control.
My way has been to take my personality type (as determined by Jung-derived personality tests such as the Myers-Briggs Type Indicator and the Kiersey Temperament Sorter) seriously and look at the choices I make in my life and the consequences...think about the feedback that people (especially significant others in my life) give me and take it seriously too. I have studied my dreams and found my faults set to mini-dramas that I cannot deny.
Introspection is key here and also, perhaps, a tried and true wisdom for how to open up and admit to yourself what yourself, others and your unconscious has to say about who you are and what you choose to do.
On another note, I am an over-eater though I have not been too obese. I took on the challenge of lowering my weight (I'm 5'9'' and once weighed in at about 200 lbs) by about 40 lbs over the course of many years (over six). The two lessons I have learned that works wonders to reduce those momentary desires and cravings that on a daily basis keep one at the weight one is at are:
- Exercise at a cardio level for 20+ minutes
- Find the short-term consequence of choosing to eat something you shouldn't eat
- Substitute for what you want in order to enable the ability to choose what you need
Exercise at a cardio level is apparently the only way to improve one's metabolism such that one can do more with less food. Not exercising means getting your weight down is not going to work in the long run. Exercise is the suffering you choose that allows you to avoid the suffering that having a body that is not used will bring you.
I have found that my sleep is greatly affected by what I eat. Also what I eat might cause me a headache if I eat too much. These two things have allowed me to very slowly loose my cravings for food, even free food, because I immediately can bring to mind the suffering I will experience later if I choose to eat something now.
I have gradually substituted foods making my way towards a more fulfilling diet that doesn't leave me with headaches or sleepless at night. I substituted carbonated water for soda, favorite protein foods for dessert, eat more earlier in the day rather than have a large dinner, low carb cauliflower rice for rice, low carb zucchini (zoodles) for high carb pasta, etc... The result is that I now get a regular night's sleep, through exercise I am stronger than I have ever been and as I mentioned I am now down 40lbs from my peak weight and my weight is stable.
All this is to say that we have instinctual needs and drives which MUST be satisfied. If we fight them or ignore them then we make choices which impact our health or our moral character. The belief that I am a personality with certain strengths and weaknesses who needs to work on the weaknesses and feed the strengths and never stop doing this has helped me to be a better person in my self and in my interaction with others.
