Human freedom is realised in the adoption of humanity as an end in itself, for the one thing that no-one can be compelled to do by another is to adopt a particular end. - 'Metaphysical Principles of Virtue
[O]nly if every individual strives for truth can humanity attain a happier future; the atavisms in each of us that stand in the way of a friendlier destiny can only thus be rendered ineffective.
You do not know the unfathomable cowardice of humanity...servile in the face of force, pitiless in the face of weakness, implacable before blunders, indulgent before crimes...and patient to the point of martyrdom before all the violences of bold despotism.
Whether we love humanity or not, we must realize that we are part of it. My future depends entirely on the future of humanity, and so I am compelled to take care of humanity. That is why being compassionate is actually in my own best interest. And a symptom of my own peace of mind is that I can share comfort with others around me.
If humanity is to survive, happiness and inner balance are crucial. Otherwise the lives of our children and their children are more likely to be unhappy, desperate and short. Material development certainly contributes to happiness - to some extent - and a comfortable way of life. But this is not sufficient. To achieve a deeper level of happiness we cannot neglect our inner development.
There are some who esteem that it is a naivety to believe that a moral regeneration may be possible ("soit possible", Fr.); now, if this was not the case, it would not be worth the trouble that humanity continue to vegetate without aim.
If a man, before he passed from one stage to another, could know his future life in full detail, he would have nothing to live for. It is the same with the life of humanity. If it had a programme of the life which awaited it before entering a new stage, it would be the surest sign that it was not living, nor advancing, but simply rotating in the same place.
