But as for us, we observe that there are degrees in every kind of evil, and especially in the indeterminate and undefined kind that has to do with the soul. (In the same way also there are different degrees of progress produced by the abatement of baseness like a receding shadow, as reason gradually illuminates and purifies the soul.) We do not, therefore, think that consciousness of the change is unreasonable in the case of persons who are, as it were, making their way upward out of some deep gorge, but that there are ways in which it can be computed. Of these I beg you to consider the first without further preface. Just as men sailing out into the open sea calculate their run by the time elapsed in conjunction with the strength of the wind, reckoning how much distance, after spending a certain time, while carried onward by a certain force, they are likely to have accomplished; so too in philosophy a man may take for himself as a proof that he is gaining ground the uniformity and continuity of his course, which makes on the way no frequent halts, followed by leaps and bounds, but smoothly and regularly forges ahead, and goes through the course of philosophic reasoning without mishap. For the lines: If even small upon the small you place And do this oft, Hesiod, Works and Days , 361. Quoted more fully supra , 9 E. are not merely well put in regard to the increase of money, but they apply to everything, and especially to advancement in virtue, since reason thereby gains the aid of constant and effective habit. But the variation and obtuseness often shown by students of philosophy not only cause delays and stoppages in their progress on the road to knowledge, but also bring about retrogressions, since vice always makes an onset on the man who yields ground by loitering, and carries him backward in the opposite direction. Mathematicians tell us that the planets, when their forward movement ceases, become for the moment stationary, but in the study of philosophy there is no intermission when progress halts, nor any such thing as remaining stationary, but Nature, being never free from motion of some sort, is wont to move up or down, as though suspended on a balance, and to be swayed by the better motives, or else under the influence of the contrary motives it moves rapidly towards what is worse. If therefore you follow the advice given by the god in the oracle, to fight the Cirrhaeans all days and all nights, and are conscious that you likewise in the daytime and the nighttime have always carried on an unrelenting warfare against vice, or at least that you have not often relaxed your vigilance nor constantly granted admission to divers pleasures, recreations, and pastimes, which are, as it were, envoys sent by vice to treat for a truce, it is then quite probable that you may go on with good courage and confidence to what still remains. However, even though it be that intermissions occur in one’s philosophical studies, yet if the later periods of study are more constant and long-continued than they were earlier, Some editors would amenδ the text here, and perhaps rightly, to make the text correspond better to what the sense plainly requires. this is no slight indication that the spirit of indifference is being expelled through industry and practice; but there is something pernicious in the opposite condition, when numerous and continued set-backs occur after no long time, as if the spirit of eagerness were withering away. We may compare a reed, the growth of which at its beginning has a very great impetus, which results in an even and continuous length, at first in long sections, since it meets with few obstacles and repulses, but later, as though for lack of breath as it gets higher up, it grows weak and weary, and is gathered up in the many frequent nodules, when the life-giving spirit meets with buffets and shocks; so with philosophy, those who at the outset engage in long excursions into its realms and later meet with a long series of obstacles and distractions without becoming aware of any change toward the better, finally get wearied out, and give up. But a man of the other type is again given wings Homer, Iliad , xix. 386. by the help he gets as he is carried onward, and by the strength and eagerness born of successful accomplishment brushes aside pretences as though they were a hindering crowd in his path. In the same way that an indication of the beginning of love is to be found, not in the taking delight in the presence of the loved one (for this is usual), but in feeling a sting of pain when separated; just so are many allured by philosophy and seem to take hold of the task of learning with high aspirations, but if they are forced by other business and occupations to leave it, all that excitement of theirs subsides and they no longer care. But He in whose heart the prick of youthful love Nauck, Trag. Graec. Frag., Sophocles , No. 757; cf. Plutarch, Moralia , 619 A. is planted may appear to you moderate and mild while present at philosophical discussions; but when he is separated and apart from them, behold him ardent and troubled, and dissatisfied with all business and occupations, and, cherishing the mere recollection, he is driven about like an irrational being by his yearning towards philosophy. For we ought not to enjoy being present at discussions as we enjoy the presence of perfumes, and then when we are removed from them not seek after them or even feel uneasy; but we ought in our periods of separation to experience a sensation akin in a way to hunger and thirst, and so be led to cleave to what makes for real progress, whether it chance to be a wedding or wealth or the duties of friendship or military service that causes the temporary parting. For the greater the acquisition from philosophy is, the more annoyance there is in being cut off from it. Quite the same as this, or nearly the same, is the very ancient elucidation of progress found in Hesiod, Works ad Days , 289. which sets forth that the way is no longer uphill, nor very steep, but easy and smooth and readily accomplished, as though it were made smooth by practice, and as though it brought on a light, which is to be found in the study of philosophy, and an illumination succeeding upon perplexity, errant thought, and much vacillation, which students of philosophy encounter at the outset, like persons who have left behind the land which they know and are not yet in sight of the land to which they are sailing. For having given up the common and familiar things before gaining knowledge and possession of the better, they are carried hither and thither in the interval, and oftentimes in the wrong direction. An illustration is the story told about Sextius, the Roman, to the effect that he had renounced his honours and offices in the State for philosophy, but, because he was impatient and found the subject difficult at the outset, he came very near throwing himself down from an upper story. A similar tale, too, they record about Diogenes The story is found also in Aelian, Var. Hist. xiii. 26. of Sinope at the beginning of his devotion to philosophy. The Athenians were keeping holiday with public banquets and shows in the theatre and informal gatherings among themselves, and indulging in merry-making the whole night long, while Diogenes, huddled up in a corner trying to sleep, fell into some very disturbing and disheartening reflexions how he from no compulsion had entered upon a toilsome and strange mode of life, and as a result of his own act he was now sitting without part or parcel in all these good things. A moment later, however, a mouse, it is said, crept up and busied itself with the crumbs of his bread, whereupon he once more recovered his spirits, and said to himself as though rebuking himself for cowardice, What are you saying, Diogenes ? Your leavings make a feast for this creature, but as for you, a man of birth and breeding, just because you cannot be getting drunk over there, reclining on soft and flowery couches, do you bewail and lament your lot ? Now when such fits of dejection become of infrequent occurrence and the objections and protests made by sound sense against them quickly come to our help, as though rallying after a temporary rout, and easily dissipate our depression and dismay, we may well believe that our progress rests on a firm foundation.
