<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I find it hard also to pick a greatest as there are so many great writers who have buoyed the genre in different areas. I like stories that uses SciFi as a means to lay bare the human psyche, so love P. K. Dick. Robert Silverberg and Theodore Sturgeon have also produced great works in this vein. When I feel like hard SciFi, it is hard to beat Arthur C. Clarke and Isaac Asimov, but I think Greg Bear deserves a mention. I love the English language and few can eclipse M. John Harrison for the beauty of his writing - so he is on my list of greatest writers. For sheer story - telling wonder: Jack Vance and Peter F. Hamilton. <br /> Posted by jmilsom</DIV></p><p>In the 1990's it was the "killer B's" that were considered the top hard sci-fi writers: David Brin, Gregory Benford, and Greg Bear. Alas, they have not been as productive lately, but all have produced some of my favorite hard science fiction novels. Most notably, Brin's Uplift Series (<span style="font-style:italic" class="Apple-style-span">Startide Rising, Sundiver, The Uplift War</span>, etc.), Benford's Galactic Center series (<span style="font-style:italic" class="Apple-style-span">In The Ocean of Night, Across the Sea of Suns, Tides of Light</span>, etc.), and Bear's <span style="font-style:italic" class="Apple-style-span">Forge of God</span> series, as well as numerous stand-alone novels such as <span style="font-style:italic" class="Apple-style-span">Moving Mars</span> (my personal favorite!) <span style="font-style:italic" class="Apple-style-span">Hegira</span>, and <span style="font-style:italic" class="Apple-style-span">Blood Music</span>.</p> <div class="Discussion_UserSignature"> </div>
