De Migratione Abrahami

The mind, therefore, going forth out of the places which are in Charran, is said "to have travelled through the land until it came to the place of Sichem, to a lofty oak." [*](Genesis xii. 6. ) And let us now consider what this travelling through the land means. The disposition which is fond of learning is inquisitive and exceedingly curious by nature, going everywhere without fear or hesitation and prying into every place, and not choosing to leave anything in existence, whether person or thing, not thoroughly investigated; for it is by nature extraordinarily greedy of everything that can be seen or heard, so as not only not to be satisfied with the things of its own country, but even to desire foreign things which are established at a great distance.

At all events, they say that it is an absurd thing for merchants and dealers to cross the seas for the sake of gain, and to travel all round the habitable world, not allowing any considerations of summer, or winter, or violent gales, or contrary winds, or old age, or bodily sickness, or the society of friends, or the unspeakable pleasures arising from wife, or children, or one’s other relations, or love of one’s country, or the enjoyment of political connections, or the safe fruition of one’s money and other possessions, or, in fact, anything whatever, whether great or small, to be any hindrance to them; [*](Genesis xxx. 30. ) [*](Exodus i 21 ) [*](Genesis xii. 6. )

and yet for men, for the sake of that most beautiful and desirable of all possessions, the only one which is peculiar to the human race, namely, wisdom, to be unwilling to cross over every sea and to penetrate every recess of the earth, inquiring whenever they can find anything beautiful either to see or to hear, and tracing out such things with all imaginable zeal and earnestness, until they arrive at the enjoyment of the things which are thus sought for and desired.

Do thou then, O my soul, travel through the land, and through man, bringing if you think fit, each individual man to a judgment of the things which concern him; as, for instance, what the body is, and under what influences, whether active or passive, it co-operates with the mind; what the external sense is, and in what manner that assists the dominant mind; what speech is, and of what it becomes the interpreter so as to contribute to virtue; what are pleasure and desire; what are pain and fear; and what art is capable of supplying a remedy for these things; by the aid of which a man when infected with these feelings may easily escape, or else perhaps may never be infected at all: what folly is, what intemperance, what committing injustice, what the whole multitude of other diseases, which it is the nature of all destructive vice to engender; and also what are the means by which they can be averted. And also, on the contrary, what justice is, what prudence is, and temperance, and manly courage, and deliberate wisdom, and in short what each virtue is, and what the mastery over the passions is, and in what way each of these virtues is usually produced.

Travel also through the greatest and most perfect being, namely this world, and consider all its parts, how they are separated in respect of place and united in respect of power; and also what is this invisible chain of harmony and unity, which connects all those parts; and if while considering these matters, thou canst not easily comprehend what thou seekest to know, persevere and be not wearied; for these matters are not attainable without a struggle, but they are only found out with difficulty and by means of much and great labour;
