Concept:
Immanuel Kant tried to combine rationalism and empiricism.
He accepted that experience is important, but he also argued that the mind contributes certain forms and categories to knowledge.
Step 1: Understand the statement.
The statement says:
\[
\text{Knowledge begins with experience}
\]
but:
\[
\text{Knowledge does not completely arise from experience}
\]
This means experience starts the process, but the mind also plays an active role.
Step 2: Connect with Kant.
Kant famously argued that although all our knowledge begins with experience, it does not follow that all knowledge arises from experience.
This is central to his critical philosophy.
Step 3: Compare with other philosophers.
Locke was an empiricist and emphasized experience.
Descartes was a rationalist and emphasized reason.
Plato emphasized knowledge of forms.
The exact statement is connected with Kant.
Hence:
\[
\boxed{\text{Kant}}
\]
