Impact of losing adab
One of the best definitions of adab i have seen is that by prof seyyed naquib al-attas whereby he defines it generally as discipline of body, mind and soul.
This discipline has to be inculcated in a person from his/her birth all through years of growing up till he/she dies. Indeed the learning process is a lot more intensive in his/her earlier years of life. The classroom for learning adab is the world itself and beyond. The teachers start from parents, extend to siblings, relatives, kinsmen, neighbours and include various forms of institutions which come in a little later and the process never stops.
Now in today's world this classroom for adab has fallen apart. Naturally explaining the loss of adab in ourselves as a human race. The impact now becomes obvious. Without adab, the impact will be a loss of justice. Today due to lack or loss of adab, we cant engage anything from environment, to other humans, to other countries, to systems etc positively. Instead we end up exploiting, destroying, harming, abusing, corrupting and stealing. Naturally the response from the other end will not be pleasant having received nothing pleasant from us. But we remain oblivious and defiant in our ways blaming everyone and everything except ourselves. If mankind wants to resolve any one of its woes, it has to at least re-estalish whatever adab that it lost, instead of finding inspiration in alternative ideologies such as secularism, liberalism which only add on to the erosion of adab and exacerbating the woes.
