|Time: A. Time is a dimension in which events are arranged. At first, no direction (before / after) is defined with this. A time direction can be obtained in the context of the Second Principle of Thermodynamics. However, a global framework must be assumed, within which there is an increase of entropy. The assumption of increasing entropy does not apply to the comparison of local events. B. In the case of the subjective time, the question of direction is less problematic. The perceived time direction is expressed by the learned use of the terms "before" and "after". See also time arrow, time travel, time reversal, symmetry, duration, space time, relativity theory, four-dimensionalism, world lines._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Peter Geach on Time - Dictionary of Arguments
Time/GeachVsQuine: Vs time cuts, Vs "hours-thick sclices" (> four dimensionalism). - Space/time are not equal axes - otherwise temperature curves would be the same as "world lines" in the "temperature-time continuum". - It is not true that quantifiers can only be applied to four-dimensional space-time points.
Space/time/Geach: are radically different: that the expression "between" is used in both, is misleading - spatial order: affects individual objects. - Temporal order: what is ordered here is represented by complex sentences. - Geach: in the temporal, ever more complex structures can be built, not in the spatial. - e.g. "x is between (y is over w) and z" makes no sense.
Time/Modal logic/Geach: I am convinced that the basic time determinations "before", "after", etc. belong to the formal logic. - I think they have to do with "possible" and "necessary". - One has claimed that a world in which the modus ponens no longer applies can be described as a world in which the time is two-dimensional or the past can be changed. - If the basic truths about time are logical, then a differently temporal world would be a chimera._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
