n. 空想家,理想主义者;唯心主义者
adj. 理想主义的;唯心主义的
It seems even incredible, that any Idealist in any age could forget himself so far as to run his head against a post, merely because he found in his system, that no external world does exist, and that therefore nothing could be without to hurt him. [F.A. Nitsch, "A General and Introductory View of Professor Kant's Principles," 1796]Earlier still, "one who holds doctrines of philosophical idealism" (1701).
