- What method of philosophical inquiry did Socrates pioneer?
- The elenchus or Socratic method: questioning people about their beliefs to expose contradictions and lead them toward truth.
- According to Socrates, what is the relationship between virtue and knowledge?
- Virtue is knowledge; wrongdoing comes from ignorance, and no one willingly does evil.
- What were the main charges against Socrates in his trial, and what was his sentence?
- Corrupting the youth and impiety toward the gods; sentenced to death by drinking hemlock.
- What is Plato's Theory of Forms (or Ideas)?
- Immaterial, eternal, unchanging abstract objects exist beyond the physical world; physical particulars are imperfect copies or instances of these universal Forms.
- Describe Plato's Allegory of the Cave.
- Prisoners chained in a cave see only shadows on a wall cast by firelight; the shadows represent sensory experience, and ascending to sunlight represents the journey to knowledge of reality.
- What did Plato believe about the immortality of the soul?
- The soul is immortal and existed before birth in a state of knowledge of the Forms; learning is recollection (anamnesis) of what the soul already knows.
- How did Aristotle differ from Plato regarding the nature of reality?
- Aristotle rejected the existence of a separate realm of Forms; he argued that universals exist only in individual substances, which are the primary reality.
- What are Aristotle's four causes, and what does each explain?
- Material (what something is made of), formal (its shape or essence), efficient (what brought it into being), and final (its purpose or end).
- What is Aristotle's concept of entelechia (actuality), and how does it relate to potentiality?
- Entelechia is the realization or fulfillment of potential; an entity's form or essence. Actualization is the process of moving from potentiality (what something can be) to actuality (what it is).
