2. Some[51] hold that distant objects seem to us lesser only because they are seen under a smaller visual angle. Elsewhere[52] we have shown that this is wrong; and here we shall limit ourselves to the following considerations. The assertion that a distant object seems less because it is perceived under a smaller visual angle supposes that the rest of the eye still sees something outside of this object, whether this be some other object, or something external, such as the air. But if we suppose that the eye sees nothing outside of this object, whether this object, as would a great mountain, occupy the whole extent of the glance, and permit nothing beyond it to be seen; or whether it even extend beyond the sweep of the glance on both sides, then this object should not, as it actually does, seem smaller than it really is, even though it fill the whole extension of the glance. The truth of this observation can be verified by a mere glance at the sky. Not in a single glance can the whole hemisphere be perceived, for the glance could not be extended widely enough to embrace so vast an expanse. Even if we grant the possibility of this, and that the whole glance embraces the whole hemisphere; still the real magnitude of the heaven is greater than its apparent magnitude. How then by the diminution of the visual angle could we explain the smallness of the apparent magnitude of the sky, on the hypothesis that it is the diminution of the visual angle which makes distant objects appear smaller?

Does Happiness Increase With Time?[53]
HAPPINESS HAS NOTHING TO DO WITH DURATION OF TIME.
1. Does happiness increase with duration of time? No: for the feeling of happiness exists only in the present. The memory of past happiness could not add anything to happiness itself. Happiness is not a word, but a state of soul. But a state of soul is a present (experience), such as, for instance, the actualization of life.
HAPPINESS IS NOT THE SATISFACTION OF THE DESIRE TO LIVE.
2. Might happiness not be the satisfaction of the desire of living and activity, inasmuch as this desire is ever present with us? (Hardly). First, according to this hypothesis, the happiness of to-morrow would ever be greater than that of to-day, and that of the following day than that of the day before, and so on to infinity. In this case, the measure of happiness would no longer be virtue (but duration). Then, the beatitude of the divinities will also have to become greater from day to day; it would no longer be perfect, and could never become so.[54] Besides, desire finds its satisfaction in the possession of what is present, both now, and in the future. So long as these present circumstances exist, their possession constitutes happiness. Further, as the desire of living can be no more than the desire to exist, the latter desire can refer to the present only, inasmuch as real existence (essence) inheres only in the present. Desire for a future time, or for some later event, means no more than a desire to preserve what one already possesses. Desire refers neither to the future nor the past, but to what exists at present. What is sought is not a perpetual progression in the future, but the enjoyment of what exists from the present moment onward.
INCREASED HAPPINESS WOULD RESULT ONLY FROM MORE PERFECT GRASP.
3. What shall be said of him who lived happily during a longer period, who has longer contemplated the same spectacle? If such longer contemplation resulted in a clearer idea thereof, the length of time has served some useful purpose; but if the agent contemplated it in the same manner for the whole extent of time, he possesses no advantage over him who contemplated it only once.
