Answer:
According to Elie Wiesel, the Holocaust survivor and human rights activist, indifference means to be unconcerned or unresponsive to the suffering of others. It is a lack of empathy and compassion, and a failure to take action in the face of injustice or suffering.
The opposite of indifference is concern or engagement. This means being aware of the suffering of others and being motivated to take action to help or alleviate that suffering. It involves showing empathy and compassion towards others, and being willing to stand up for what is right and just.
In my own words, indifference means being disengaged or disinterested in the struggles and experiences of others, while the opposite of indifference is actively caring about and seeking to make a positive impact on the world around us. It is about recognizing and valuing the humanity of others, and working towards a more compassionate and just society.
