So, I am asking how relevant is for us to consider now? — Jack Cummins
To me, compassion is a virtue. It is a feeling, quality, or a kind of state of mind. As others have mentioned, I believe compassion is synonymous with the expression of empathy. Although, that may not be the only conception of compassion.
Whether or not compassion by itself can bring about tangible remedies to suffering without action to back it up is in question. NOS4A2 sums it up well:
But compassion, as a feeling, is nothing if it isn’t followed by good deeds. — NOS4A2
A less extreme version of the point indicated by the quote is well-taken on my end. Feelings by themselves do not solve the "seemingly intractable problems of our times". Those may be too large-scale to solve without collective action.
Yet, I do not think compassion is worth "nothing" without good deeds to follow it. I think good intentions normally (but certainly not always) are prior to good action. If compassion is in the philosophical trash bin as you worry, then I do not think it deserves to be there. After all, since compassion can
motivate someone to palliate the suffering of another, then compassion is a harbinger of goodness in the world in at least a minimal sense. But as NOS4A2 brought up, someone who feels empathy may nevertheless not act upon that feeling, often because they do not have the means to do so effectively. In cases like that, while compassion may be helpful ( and perhaps necessary) to develop the kinds of human beings who wish to alleviate suffering, compassion alone may not be enough to solve the "world's problems". Perhaps all that is why compassion might appear rather underrated in philosophical communities.
On another level, what exactly the "intractable" problems in need of solving are seems up for debate. Such problems do not seem delineated in the original post. Yet this is an important clarification to make: what counts as "goodness" or a "problem" in the contexts of actions and people might be totally relative to your audience.
In my opinion, in the final analysis, the solution to the intractable problems of our times, whatever they are, must take place due to tangible, noticeable, and positive change in rules and institutional structures. That is a feat achieved by - but not only by - a change of heart.
