Anger is the ultimate troublemaker. I feel you can express a strong disapproval or dislike of an object without losing your temper.

Too much of a self-centered attitude creates mistrust and suspicion in others, which can in turn lead to fear. But if you have more of an open mind, and you cultivate a sense of concern for others' well-being, then, no matter what others' attitudes are, you can keep your inner peace.

Religious belief is not a precondition either of ethical conduct or of happiness.

True friends share genuine closeness and remain friends irrespective of fluctuating fortunes.

Without religion, also there is a way, it could be this way, through education, through scientific findings, then you get conviction. Not necessarily really love other, but for their own interest they are showing love, compassion to other like that.

An ethical act is one which does not harm others' experience or expectation of happiness.

If there's good, strong evidence from science that such and such is the case and this is contrary to Buddhism, then we will change.
