1 An ‘emergent’ property of a whole differs from a ‘resultant’ in that whereas the latter has an intelligible, mathematical relationship with the properties of the parts, the former does not. There are no really convincing instances of such ‘emergence’ that are not simply versions of the very puzzle, the so-called Hard Problem of Consciousness, that we face: a problem created, as I suppose, by first imagining a merely material world and then being surprised that once purged of any so-called ‘secondary’ qualities it has no intelligible connection with those same ‘secondary’ (but for us immediate) properties themselves.

12 Plotinus, Ennead III.8 .8,32–36. Armstrong interprets the ‘heaviness’ as that of drunken sleep (as is possible), but there may be reason to suspect instead that it is the ‘heaviness’ of pregnancy, as Stephen Mackenna preferred in his translation of the Enneads (The Enneads edited by J. Dillon (Harmondsworth: Penguin, 1991); an abridged edition of the original Faber 1956 edition); see also Ennead VI.7 .15.
13 Ennead IV.4 .3: ‘memory’, in this context, indicates that our soul is now conscious of something that is not present to it in the way that reality is present to an eternal view (on which, more below).
14 See Aquila, Richard E., ‘On Plotinus and the “Togetherness” of Consciousness’, Journal of the History of Philosophy 30 (1992), 7–32.

16 ‘Talking’, they suppose (?), is simply voicing strings of symbols, rather than any strongly intentional act: once our computers can simulate a conversation ‘well enough’ they will be held to be ‘conscious’ in the only way that anything can ‘really’ be. Cf. Hannay, Alastair, ‘Comments on Honderich, Sprigge, Dreyfus and Rubin, and Elster’ in Synthese 98 (1994), 95–112: ‘If I should ever deny the existence of consciousness or begin to agree that the presently extant theories, including all extant versions of functionalism, provide adequate accounts of all we ever need to know or imply by saying we are conscious, I trust there will be some independent evidence that I have lost my mind’ (99).
17 So also in the Hermetic Corpus 9.1–2: ‘there is no evidence of understanding without reasoned speech. … and without understanding it is impossible to have sensation’ (translated by Copenhaver, Brian P., Hermetica (Cambridge: Cambridge University Press, 1992), 27).
18 Carruthers, Peter, Language, Thought and Consciousness: an Essay in Philosophical Psychology (Cambridge: Cambridge University Press, 1996), 158. Carruthers goes on to suggest that conscious awareness of its own states could only evolve and persist in conjunction with a capacity to distinguish appearance and reality. So an omniscient being, presumably, for which there is no such distinction, must be unconscious.
19 Cf. Sprigge, T. L. S., ‘Final Causes’, Aristotelian Society Supplementary Volume 45 (1971), 149–70, introducing the notion ‘what it is like to be something’. See also Washburn, A. L., The Animal Mind, 2nd ed. (New York: Macmillan, 1917), 3ff., on what it is like to be a wasp.

21 Ennead V.3 .5, 44. All Neo-Platonists distinguish the One and the Intellect: the latter is essentially complex in that thinking and the objects thought are distinct, and the objects of thought, the whole interconnected system of intelligible reality, are many. They are unified through the presence of ‘the One’, which lies beyond both intellect and being (as Plato said: Republic 6.509b).
24 Actually, Plotinus takes considerable pains to be clear, and criticises those who don't: see especially II.1 .1, II.9 .15, and Porphyry, Life of Plotinus 13, on his response to Thaumasius' wish for general statements. But his readers don't always do him justice.

27 Few of us can see many more than seven or eight such sheep as a Gestalt: angels, presumably, see any number of things like that.

29 Ennead V.8 .5f, citing Plato, Symposium 215b; see also Ennead IV.3 .11. It is commonly suggested that Plotinus is here mistaking the nature of hieroglyphs, but there is good reason, despite later oversimplifications or inventions (on which see Hornung, Erik, The Secret Lore of Egypt: its Impact on the West, translated by Lorton, David (Ithaca and London: Cornell University Press, 2001)), to think that he got it right. ‘The Egyptians do not hesitate to call hieroglyphs “gods”, and even to equate individual signs in the script with particular gods; it is quite in keeping with their views to see images of the gods as signs in a metalanguage. As is true of every Egyptian hieroglyph, they are more than just ciphers or lifeless symbols; the god can inhabit them, his cult image will normally be in the same form, and his priests may assume his role by wearing animal masks’ (Hornung, Erik, Conceptions of God in Ancient Egypt: the One and the Many, translated by Baines, John (Ithaca: Cornell University Press, 1982), 124).
30 Ennead III.7 .4. See also Ennead V.5 .1: ‘They [sc. truth and the intelligible] are certainly not “premises” or “axioms” or “expressions”; for then they would only say something about other things and would not be the things themselves, as when [one says] “Justice is beautiful”, though justice and beauty are different [from the words used].’

(London: Routledge & Kegan Paul, 1980), 33: working on Zen koans has the object of extending enlightenment from the mind's eye through the whole body, so that ‘the whole body is an eye’. Kadowacki (Ibid., 13, 49) also emphasises the body language that precedes ‘oral speech’.

46 In Hilary Armstrong's words: ‘Plotinus' divine mind is not just a mind knowing a lot of eternal objects. It is an organic living community of interpenetrating beings which are at once Forms and intelligences, all “awake and alive”, in which every part thinks and therefore is the whole; so that all are one mind and yet each retains its distinct individuality without which the whole would be impoverished. And this mind-world is the region where our own mind, illumined by the divine intellect finds its true self and lives its own life, its proper home and the penultimate stage on its journey, from which it is taken up to union with the Good’ (Armstrong, A. H. and Markus, R. A., Christian Faith and Greek Philosophy (London: Darton, Longman & Todd, 1960), 27).

56 Ennead VI.7 .35. This is closer to the thesis of The Cloud of Unknowing than to that of Ps-Dionysius. ‘For Denys the divine darkness lies beyond the farthest effort of the mind, and it is the mind (the nous) that enters it: for the author of the Cloud, we enter the cloud of unknowing when we renounce the activity of the mind and rely solely on “the loving power” of the soul’: Louth, Andrew, Denys the Areopagite (London: Continuum, 1989), 125.

75 I should add – merely to avoid misunderstanding - that Plotinus reckons that ‘if [lovers] remain chaste there is no error in their intimacy with the beauty here below, but it is error to fall away into sexual intercourse’: Ennead III.5 .1, 36f.

81 Weil, Simone, Notebooks, translated by Wills, A. (London: Routledge & Kegan Paul, 1956), Vol.2, 423. This thought is not to be taken lightly: it is difficult not to see in it one aspect of Weil's fatal anorexia, but her insights should not be ignored merely because, as it so often does, ‘the disease’ (that is, the demon) took advantage of them. When she wrote that ‘I cannot conceive of the necessity for God to love me, when I feel so clearly that even with human beings affection for me can only be a mistake. But I can easily imagine that he loves that perspective of creation which can only be seen from the point where I am… I must withdraw so that he can see it. I must withdraw so that God may make contact with the beings whom chance places in my path and whom he loves’ (Weil, Simone, Gravity and Grace (Lincoln, NE: University of Nebraska Press, 1952), 88), the disease was speaking. How could it be that God loved everything but Weil? See also Lippitt, John, ‘True self-love and true self-sacrifice’, International Journal of Philosophy of Religion 64–5 (2009).
82 The punning relationship of aletheia, truth, and lethe, forgetfulness, is founded on a false etymology, but still has some force: see my God's World and the Great Awakening (Oxford: Clarendon Press, 1991), 48–54.

In it is nonbeing really an excess of being. It is not a life, but is, rather, superabundant Life. It is not a mind, but is superabundant Wisdom.… And one might even say that nonbeing itself longs for the Good which is above all being.’
93 E. Hornung, Conceptions of God in Ancient Egypt, op. cit., 253.
94 This collapse of boundaries, ‘the death of the “I” as knower, chooser, and doer’, is the sinister image of the Plotinian ascent: see John E. Nelson, Healing the Split, op. cit., 43. In a way the psychotic is correct: reality is larger than we know, and full of demons. But if Plotinus is correct, so also was Housman, in his more optimistic mode: ‘The world is round, so travellers tell,/ And straight though reach the track,/ Trudge on, trudge on, ‘twill all be well,/ The way will guide one back’ (Housman, A. E., ‘A Shropshire Lad’ 36 in Collected Poems (Harmondsworth: Penguin, 1956; 1st published 1939), 65).
