My focus is on Team Humanity not on ‘humanism’ as it is understood at present. I do agree with many aspect of ‘Humanism’ as defined at present but not totally.
The limitation is the current ideology of Humanism focus on human beings as individuals and in loose groups but not in the sense of a ‘Team’.
A ‘team’ is generally defined as;
“[a] team is a group of people who are interdependent with respect to information, resources, and skills and who seek to combine their efforts to achieve a common goal”
en.wikipedia.org/wiki/Team
In the case of Team Humanity, the team comprised on every individual humans on Earth [or in space] aligned to common goals with the best of their ability.
Note I mentioned such a Team Humanity is not efficient in the present circumstances but I am confident it is possible in the future.
Actually it is possible to sense such a possibility of Team Humanity. For if suddenly the astronomers discovered a rogue asteroid the size of the USA heading towards Earth and which could split the Earth into pieces, such knowledge if announced to the world will definitely trigger a sense of Team Humanity to try to work as one to save the Earth and the humans therein. Unfortunately having a sense of Team Humanity out of emergency is not the way to go and in addition this is not sustainable if the asteroid missed Earth.
To strive toward achieving, maintaining and sustaining Team Humanity, a lot of strategies and processes need to be done and I think they are feasible given the trend of the current exponential expansion of knowledge and technology [esp IT and AI].
Here are some of the targets that need to be achieved for the average human being;
If the average IQ at present is 100, then we need to increase to 150, 200, 250 incrementally over a certain period of time.
It the same for emotional intelligence [EQ], if the average is 100, then we have to increase to 500, 600, 1000 over a certain period.
It is also the same for other human quotients, e.g. spirituality [SQ], rationality, wisdom [QWQ], morality [MQ], ethical philosophy [PQ], teambuilding [TQ] and various quotients where we need to increase the average by at least 3-5 folds.
We have already has a trend of increments for the above average quotients if compared to 1000 years ago, so it is possible to achieve the targets above given the current knowledge and technological advances.
Once the there is an increasing trend for the various quotients, then there will emerge Team Humanity spontaneously with continual increments.
Note if the average theoretical and practical philosophical quotient including morality and ethics is increased by 1000%, then we can ensure the strategies will be fool proof against evil and will be continually optimized.
In the above sense, yes, Team Humanity [with subset humanism] will be objectively superior to egoism, familialism and ethnocentrism.
Btw, Team Humanity must not survive at the expense of other living things since all living things are interdependently connected to all.
We can rely on thinkdr and Dr. Hartman’s axiology to provide the objective measures in terms of quantified values on the above.
