Who knoweth the spirit of man that goeth upward, and the spirit of the beast that goeth downward to the earth? The statement is here too categorically rendered, though, for dogmatical purposes, the Masorites seem to have punctuated the text with a view to such interpretation. But, as Wright and others point out, the analogy of two other passages (Ecclesiastes 2:19 and Ecclesiastes 6:12), where "who knoweth" occurs, intimates that the phrases which follow are interrogative. So the translation should be, "Who knoweth as regards the spirit (ruach) of the sons of men whether it goeth upward, and as regards the spirit (ruach) of the beast whether it goeth downward under the earth?" Vulgate, Quis novit si spiritus, etc.? Septuagint, τίς εἷδε πνεῦμα υἱῶν τοῦ ἀνθρώπου εἰ ἀναβαίνει αὐτὸ ἄνω; "Who ever saw the spirit of the sons of man, whether it goeth upward?" The Authorized Version, which gives the Masoretic reading, is supposed to harmonize better with the assertion at the end of the book (Ecclesiastes 12:7), that the spirit returns to the God who gave it. But there is no formal denial of the immortality of the soul in the present passage as we render it. The question, indeed, is not touched. The author is confirming his previous assertion that, in one point of view, man is not superior to brute. Now he says, looking at the matter merely externally, and taking not into consideration any higher notion, no one knows the destiny of the living powers, whether God deals differently with the spirit of man and of beast. Phenomenally, the principle of life in both is identical, and its cessation is identical; and what becomes of the spirit in either case neither eye nor mind can discover. The distinction which reason or religion assumes, viz. that man's spirit goes upward and the brute's downward, is incapable of proof, is quite beyond experience. What is meant by "upward" and "downward" may be seen by reference to the gnome in Proverbs 15:24, "To the wise the way of life goeth upward, that he may depart from Sheol beneath." The contrast shows that Sheol is regarded as a place of punishment or annihilation; this is further confirmed by Psalms 49:14, Psalms 49:15, "They are appointed as a flock for Sheol: death shall be their shepherd … their beauty shall be for Sheol to consume But God will redeem my soul from the power of Sheol; for he shall receive me." Koheleth neither denies nor affirms in this passage the immortality of the soul; that he believed in it we learn from other expressions; but he is not concerned with parading it here. Commentators quote Lucretius' sceptical thought ('De Rer. Nat.,' 1.113-116)—
"Ignoratur enim quae sit natura animal,
Nata sit, an contra nascentibus insinuetur,
Et simul interest nobiscum, morte dimenta,
An tenebras Orci visat vastasque lacunas."
"We know not what the nature of the soul,
Born in the womb, or at the birth infused,
Whether it dies with us, or wings its way
Unto the gloomy pools of Orcus vast."
But Koheleth's inquiry suggests the possibility of a different destiny for the spirits of man and brute, though he does not at this moment make any definite assertion on the subject. Later on he explains the view taken by the believer in Divine revelation (Ecclesiastes 12:7).
