... What I mean by emotion felt towards a thing, future, present, and past, I explained in III. xviii., notes. i. and ii., which see. (But I should here also remark, that we can only distinctly conceive distance of space or time up to a certain definite limit; that is, all objects distant from us more than two hundred feet, or whose distance from the place where we are exceeds that which we can distinctly conceive, seem to be an equal distance from us, and all in the same plane; so also objects, whose time of existing is conceived as removed from the present by a longer interval than we can distinctly conceive, seem to be all equally distant from the present, and are set down, as it were, to the same moment of time.) VI. Quid per affectum erga rem futuram, praesentem et [excl exh triple] praeteritam intelligam, explicui in scholiis I et II propositionis 18 partis III, quod vide {non-deductive reference}. Sed venit hic praeterea notandum quod ut loci sic etiam temporis distantiam non nisi usque ad certum quendam limitem possumus distincte imaginari hoc est sicut omnia illa objecta quae ultra ducentos pedes a nobis distant seu [non-excl non-exh] quorum distantia a loco in quo sumus, illam superat quam distincte imaginamur, que longe a nobis distare et perinde ac si in eodem plano essent, imaginari solemus, sic etiam objecta quorum existendi tempus longiore a praesenti intervallo abesse imaginamur quam quod distincte imaginari solemus, omnia que longe a praesenti distare imaginamur et ad unum quasi temporis momentum referimus.
