If there are parts, then there must be a whole... what is that whole?

Who is the Philosopher?

Personal attributes of the philosopher left to own study and reflection

Suffices:

  • What is philosophy?
  • What is the proper "object" of philosophical inquiry?

How do we connect with the world reality?

  • senses (especially sight and sound)
  • memory and reason (imagination and intellect)

Platonism

There are two dimensions of reality

  • The "things" that are ever coming, becoming, and going
  • The "forms" of things themselves; universal

Opinion: of becoming

  • individual things
    • changeable
    • temporal
    • material
    • sensible (= perceptible)
  • interested in
    • instances of ...
    • some of ...
    • tokens of ...
    • part of ...
  • The lover of sights and sounds dwells here

Knowledge: of being

What is

  • unchanging
  • eternal
  • immaterial
  • intelligible

The forms/idea/ideal

  • instead of instances/some, all
  • instead of tokens, type
  • instead of parts, whole

Mathematically, one would write Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle x_i \in X}

In object-oriented programming, forms are represented by classes.
