Does the following text qualify as 'expository prose'? If yes, what are the expository elements that it contains?

He brought a new thing with him which the others do not seem to
Have had. This was mind - curiosity - the desire to find out and learn. So from
The earliest days began man's quest. Observe a little baby, how it looks at the
New and wonderful world about it; how it begins to recognize things and
People; how it learns. Look at a little girl; if she is a healthy and wide-awake
Person she will ask so many questions about so many things. Even so, in the
Morning of history when man was young and the world was new and
Wonderful, and rather fearsome to him, he must have looked and stared all
Around him, and asked questions. Who was he to ask except himself? There
Was no one else to answer. But he had a wonderful little thing - a mind - and
With the help of this, slowly and painfully, he went on storing his experiences
And learning from them. So from the earliest times until to-day man's quest
Has gone on, and he has found out many things, but many still remain, and as
He advances on his trail, he discovers vast new tracts stretching out before
Him, which show to him how far he is still from the end of his quest - if there
Is such an end.
What has been this quest of man, and whither does he journey? For thousands of years men have tried to answer these questions. Religion and philosophy and science have all considered them, and given many answers. I shall not trouble you with these answers, for the sufficient reason that I do not know most of them. But, in the main, religion has attempted to give a complete and dogmatic answer, and has often cared little for the mind, but has sought to enforce obedience to its decisions in various ways. Science gives a doubting and hesitating reply, for it is of the nature of science not to dogmatize, but to experiment and reason and rely on the mind of man. I need hardly tell you that my preferences are all for science and the methods of science.
We may not be able to answer these questions about man's quest with any
Assurance, but we can see that the quest itself has taken two lines. Man has
Looked outside himself as well as inside; he has tried to understand Nature,
And he has also tried to understand himself. The quest is really one and the
Same, for man is part of Nature. "Know thyself', said the old philosophers of
India and Greece; and the Upanishads contain the record of the ceaseless and
Rather wonderful strivings after this knowledge by the old Aryan Indians. The
Other knowledge of Nature has been the special province of science, and our
Modern world is witness to the great progress made therein. Science, indeed,
Is spreading out its wings even farther now, and taking charge of both lines of
This quest and co-ordinating them. It is looking up with confidence to the most
Distant stars, and it tells us also of the wonderful little things in continuous
Motion - the electrons and protons - of which all matter consists.
The mind of man has carried man a long way in his voyage of discovery. As he has learnt to understand Nature more he has utilized it and harnessed it to his own advantage, and thus he has won more power. But unhappily he has not always known how to use this new power, and he has often misused it. Science itself has been used by him chiefly to supply him with terrible weapons to kill his brother and destroy the very civilization that he has built up with so much labour.
