In this article Van Deventer stated that the Netherlands had a dept of honor of nearly 190 million gulden opposite the Dutch East Indies and had to pay for this dept of honor. When the Dutch East Indian budget was discussed in the House of Representatives a lot of attention was paid to Van Deventer's article, although not all members agreed with the content of the article. Van Deventer was appointed member of the editorial board of "The Gids" as of 1 January 1901. Over the next years until his death he would write numerous articles in this magazine.

On 19 September 1905 Van Deventer was elected as a Free-thinking Democratic member of the House of Representatives for the constituency Amsterdam IX and as such he emphasized his three focus points regarding Dutch East Indian policy: education, irrigation and emigration. He was also a promoter of the so-called Dutch Ethical Policy but at the same time said in a speech given in the House of Representatives on 16 November 1905, that if persuasion did not work it would be inevitable to use military force. In a series of articles in the "Soerabajasch Handelsblad" in August 1908 called "Insulinde's toekomst" he wrote about the importance of eductation and the creation of new jobs for natives on higher management levels.
