The man who is instrumental in bringing you ''Masterpiece Theatre'' believes that the United States government should remove itself from arts funding. And that would mean no future money for PBS.
No, not Alistair Cooke, but Herbert Schmertz, vice-president of public affairs for Mobil Oil and one of corporate America's most visible - and vocal - culture mavens. Under his guidance, Mobil underwrites ''Masterpiece Theatre'' and ''Mystery'' on PBS, sets up ad hoc syndication networks for other shows it wishes to sponsor, contributes to many museums and art shows throughout the country, and involves itself in underwriting concerts, ballets, and other performing arts.
Mr. Schmertz spoke at a ''Who Pays for PBS'' seminar recently at the New York Museum of Broadcasting.
''Who pays is very simple,'' he explained. ''The consumer pays. The rest of us are just hired hands for government and nongovernment institutions who have the opportunity and responsibility to take the consumer's money and put it into various things.
''The other group that pays is the taxpayer. When ad agencies spend the dollars of corporate clients, they are spending consumers' money. When I spend money for Mobil, I am spending consumers' money. The government is not spending government money (when it funds PBS), it is spending your money, and hired bureaucrats are making artistic decisions as to how taxpayers' money should be spent.
''I don't think the government should be spending taxpayers' money on what I believe is a substantial politicization of the cultural scene. Inevitably, if the government spends money, politics enters into the decisionmaking and frequently money is spent for propaganda. I don't mind public affairs programming on public television, but I do mind public money going into such programming.''
Mr. Schmertz went on to say that frequently he asks groups for a show of hands on how many favor government funding for PBS and many hands go up. Then, he asks how many would want government funds to establish a newspaper and people are appalled at the idea. Yet, in some respects, public television is no more than an electronic newspaper, he implies.
Over and over again, Mr. Schmertz reiterated his belief that ''when government spends taxpayers' money, it inevitably becomes politicized.''
