[I]n market gardening the soil is always made... Consequently, it is now a usual stipulation in the renting contracts of the Paris maraîcheres that the gardener may carry away his soil, down to a certain depth, when he quits his tenancy. He himself makes it, and when he moves to another plot he carts his soil away...

In the animal world we have seen that the vast majority of species live in societies, and that they find in association the best arms for the struggle for life: understood, of course, in its wide Darwinian sense — not as a struggle for the sheer means of existence, but as a struggle against all natural conditions unfavourable to the species. The animal species, in which individual struggle has been reduced to its narrowest limits, and the practice of mutual aid has attained the greatest development, are invariably the most numerous, the most prosperous, and the most open to further progress. The mutual protection which is obtained in this case, the possibility of attaining old age and of accumulating experience, the higher intellectual development, and the further growth of sociable habits, secure the maintenance of the species, its extension, and its further progressive evolution. The unsociable species, on the contrary, are doomed to decay.

Belief in an ice-cap reaching Middle Europe was at that time rank heresy; but before my eyes a grand picture was rising, and I wanted to draw it, with the thousands of details I saw in it; to use it as a key to the present distribution of floras and faunas; to open new horizons for geology and physical geography. But what right had I to these highest joys, when all around me was nothing but misery and struggle for a mouldy bit of bread; when whatsoever I should spend to enable me to live in that world of higher emotions must needs be taken from the very mouths of those who grew the wheat and had not bread enough for their children? From somebody's mouth it must be taken, because the aggregate production of mankind remains still so low. Knowledge is an immense power. Man must know. But we already know much! What if that knowledge — and only that — should become the possession of all? Would not science itself progress in leaps, and cause mankind to make strides in production, invention, and social creation, of which we are hardly in a condition now to measure the speed?
