Verbs not normally used in the present continuous
Solution 1:
The words on the OP list are:
- states (know, understand, remember, etc.),
- general realities (belong, fit, contain, consist, seem, etc.),
- emotions and wishes (like, love, hate, etc.)
Though experienced in a continuous aspect, they tend to transcend present time.
Examples:
- I know 15 digits of pi, because I memorized them in eighth grade, and will not forget them until my brain disintegrates.
- I belong to the human race just like my parents did, my children do, and my grandchildren will.
- I like reading, have liked it longer than I can remember, and probably always will.
States, general realities, emotions and wishes are part of the simple present aspect:
It is commonly referred to as a tense, although it also encodes certain information about aspect in addition to present time. [Discussion omitted]...
[C]ertain verbs expressing a state, such as be and know, are used in the simple present even when referring to a temporary present state. [Discussion omitted]...
- To refer to an action or event that takes place habitually. In the other hand to remark habits, general realities, repeated actions or unchanging situations, emotions and wishes. [Examples omitted]...
- With stative verbs in senses that do not use progressive aspect (see Uses of English verb forms: Progressive), to refer to a present or general state, whether temporary, permanent or habitual.
Emphasis mine
Even with active verbs, I eat, engages past, present and future simultaneously, while I am eating emphasizes the present.
